Time-zone overlap by US city for companies hiring part-time remote

What is the short answer for a busy buyer?

Choose the working window before you choose the hiring location. For a part-time role, the decision starts with a calendar: when must this person be available, and who must be available with them?

A candidate can live close to your time zone and still have no room for your afternoon shift. Another candidate can live farther east and cover your morning without changing their normal routine. Location helps you build the shortlist. The agreed schedule determines whether the hire works.

Write the role's hours in the US team's local time. Include the days worked, the required live window and any work that can happen outside it. Then ask each candidate to confirm the corresponding local hours in both seasons.

For example, a support role may need a continuous afternoon shift. A finance role may need a shared review window, with other tasks completed independently. Give those roles different schedule requirements even if their weekly hours are equal.

Companies that hire part-time remote workers should also define what happens when the shift ends. Who handles a customer reply that arrives later? Can an approval wait until the next workday? Does the manager know when to stop expecting a response?

Use this order before interviewing:

1. Name the US city whose clock governs the role.
2. Set the recurring days and paid hours.
3. Identify meetings or tasks that require live contact.
4. Convert the schedule into the candidate's local time.
5. Check seasonal clock changes and the holiday calendar.
6. Get written agreement on coverage and handoffs.

Keep that schedule in the hiring scorecard. A vague promise of "US hours" leaves too much for the candidate and manager to interpret.

Distinguish paid hours from hours available for meetings. A person hired for a morning shift may need most of that time to finish assigned work. If several teams expect access to the same person, have one manager approve the combined meeting load before interviews begin.

Also decide whether the role needs daily attendance. A weekly total spread across every weekday produces a different handoff pattern from the same total worked on selected days. Write down the pattern that the work requires before asking candidates to suggest alternatives.

What does the time-zone data say about Latin American overlap?

The tables below show shared hours when both people work from 9 a.m. to 5 p.m. in their own cities. They measure possible full-day overlap. They do not describe a candidate's availability or promise a part-time shift.

New York uses Eastern Time, Chicago uses Central Time, Denver uses Mountain Time and Los Angeles uses Pacific Time. The calculations use January 15, 2027, for US standard time and July 15, 2026, for US daylight time. City offsets and seasonal rules follow the IANA North America and South America time-zone data.

Shared hours during US standard time

These are calculated intersections of local workdays, using the linked North America and South America clock rules.

Shared hours during US daylight time

The same workday assumptions apply. Seasonal differences come from the IANA clock rules, including the South American city offsets.

Read the table against your US city

For New York, Bogotá shares the full assumed workday during US standard time. During daylight time, the shared window becomes shorter. Buenos Aires and São Paulo have more full-day overlap with New York during US daylight time than during standard time.

For Chicago, Mexico City and San José share the assumed workday during US standard time. Bogotá and Lima share it during US daylight time. A Chicago manager should check which local start time the candidate has agreed to follow.

For Denver, Mexico City and San José match the assumed workday during US daylight time. Do not apply Denver's seasonal schedule to every Mountain Time location. Arizona needs a separate check.

For Los Angeles, Tijuana matches the assumed workday in both tables. Buenos Aires and São Paulo have the narrowest shared windows among the cities shown. Their overlap falls earlier in the Los Angeles workday, which may suit morning reviews better than late customer coverage.

These city comparisons follow the North America and South America time-zone rules. They compare schedules without ranking candidate quality.

Check the actual part-time window

Suppose a Los Angeles team proposes a 9 a.m. to 1 p.m. shift. In Buenos Aires, that becomes 2 p.m. to 6 p.m. during US standard time. During US daylight time, it becomes 1 p.m. to 5 p.m. These are clock conversions using IANA North America and South America rules.

The proposed shift extends beyond the table's assumed local workday in one season. That does not rule out the candidate. It gives you a specific question to resolve before the offer: can they keep that later finish throughout the affected months?

Now consider a Chicago team proposing 9 a.m. to noon. A Mexico City candidate would work those same local hours during US standard time. During US daylight time, the local shift would be 8 a.m. to 11 a.m., under IANA North America rules. Confirm that earlier start rather than assuming the original agreement covers it.

Repeat this check with the manager's calendar open. A shared window has little value if the person who approves work spends it in other meetings.

Keep meal breaks and focused work visible. If the whole shared window fills with meetings, the candidate may have no paid time left to act on decisions. Decide which meetings require attendance and which can become written updates.

Use named city time zones in calendar invitations. A fixed UTC offset can become wrong when a participating city changes clocks. Mexico City stays at UTC-6, while Tijuana follows US daylight saving changes. Bogotá stays at UTC-5; Buenos Aires and São Paulo stay at UTC-3. These rules are recorded in IANA's North America and South America data.

Plan holidays separately from clock overlap

Matching clocks does not establish that both people will work on the same date. Compare the holiday calendar with the worker's recurring days before promising customer coverage.

This site is an Opus-owned reference; recommendations are editorial. Use the Opus LatAm holiday planner to review dates alongside your team calendar. Ask the employment provider to confirm which holidays apply to the individual arrangement.

For each affected workday, record who handles urgent work and whether a deadline should move. Do not assume the worker will make up holiday hours later. Ask the provider to explain the applicable treatment before putting that expectation in the schedule.

Check the first month of work as well as the annual calendar. A holiday during onboarding may affect access setup, training or the first review. Assign those tasks to dates when the hire and the person helping them are both scheduled to work.

How do the hiring models differ here?

The time conversion stays the same across hiring models. What changes is who finds the candidate, who handles employment and who resolves a schedule mismatch.

An EOR can handle employment when you already have a candidate and need a legal employer in their country. A recruiter helps find someone when you can handle employment yourself. Those distinctions appear in the Opus hiring-model comparison.

When comparing employer of record companies, separate employment support from candidate availability. Ask each provider to show where its responsibilities begin and end. A payroll arrangement does not establish that a candidate can attend your weekly planning meeting.

With a recruiter, make the schedule a screening condition before interviews. Otherwise, your team can spend time assessing someone who cannot cover the work. Include the seasonal version of the schedule in the search request.

For a managed arrangement, ask who handles a change after hiring. If the client needs later hours, who checks the worker's agreement and updates the terms? Get a clear answer before assuming the original price covers a different schedule.

For direct hiring, name an internal owner for schedule records. That person should keep the manager's calendar, the written agreement and the worker's understanding consistent.

Ask every model the same part-time pricing questions. Does the quote cover the proposed hours? What happens if those hours increase? Are there minimum commitments or separate charges? Compare written quotes for the same role and schedule.

Keep sourcing and employment decisions separate in your approval process. You can approve a candidate's skills while still needing answers about the proposed arrangement. Before making an offer, ask the employment provider to confirm that it can support the schedule in the candidate's location.

Avoid treating a small weekly workload as proof that a particular contract type fits. Describe how you expect to manage the work and ask the provider to assess the arrangement. The schedule should reflect the agreed terms before the person starts.

What should you ask a provider?

Send the schedule with the role description. Ask for a written response before spending time on a shortlist.

Ask for the candidate's recurring availability

Request the candidate's city and named time zone. Then ask for working days, local start and finish times, and any recurring commitments that affect the proposed hours.

Ask whether the candidate accepts the schedule throughout the year. A statement such as "available during US business hours" should lead to a follow-up with specific times.

Keep the questions about availability, without asking for unnecessary personal details. You need to know whether the person can cover the agreed window.

Ask how much notice either side should give before requesting a schedule change. Record who can approve it. An informal request from a teammate should not become a permanent shift change without the manager and worker agreeing.

Ask which clock governs the agreement

Choose whether the shift follows your US city's clock or the worker's local clock. That decision determines whose local hours move when a seasonal change affects the time difference.

Ask the provider to show both versions in the offer or schedule attachment. Have the candidate confirm them. Assign someone to review recurring meetings when the clocks change.

Avoid relying on abbreviations alone. A city-based calendar setting gives everyone a clearer reference than a loosely used label such as "Central."

For companies that hire part-time remote across several US offices, choose one clock for the role. List any required meetings tied to other offices separately. Otherwise, different managers may each assume that their own business hours govern the person's availability.

Ask how work moves when the shift ends

Name the person who receives unfinished work. Specify where the worker records open questions and what the next owner needs to proceed.

For engineering, this might mean a review link and a clear note about the blocked decision. For customer work, it might mean assigning the next reply before signing off.

Decide how urgent requests work outside the paid window. If the role needs extra coverage, ask the provider to explain how to arrange and price it. Do not let routine messages create an unstated on-call expectation.

Make the handoff part of the paid schedule. Ask the manager to review a sample handoff during onboarding. A useful note should let the next person act without waiting for the worker to return and explain what happened.

Ask how holidays and absences affect coverage

Request a calendar for the proposed location and start date. Compare it with release dates, month-end work and customer commitments.

Ask who confirms the applicable holiday and leave treatment. Keep that answer separate from your team's coverage plan. The employment provider may handle the employment question while your manager still needs to arrange a backup.

Ask candidates about planned availability through the agreed hiring process. Resolve known clashes before setting a start date or promising a customer handoff.

Ask for a quote tied to the actual schedule

Give every provider the same role, location assumptions and working window. Ask for the recurring charge and any conditions that change it.

Confirm how additional hours are approved. Ask what happens if your team later reduces the schedule, moves the shift or changes the scope.

Before accepting a quote, have the hiring manager walk through a sample workweek. Include the routine meetings and the time needed to finish tasks. If the workload exceeds the proposed hours, revise the role before hiring.

Use a short schedule attachment that includes:

• The governing US city and the worker's city.
• Workdays and start and finish times in both locations.
• Seasonal versions of the schedule.
• Required meetings and expected response times within the shift.
• The owner of work after the shift ends.
• The process for approving extra hours or changed hours.

Review that attachment with the finalist. Ask them to explain when their local workday begins and ends. This gives both sides a chance to catch a misunderstanding before it reaches the calendar.

Where does Opus fit for this schedule?

Opus states: "Every Opus placement works with US timezone overlap." Treat that as the starting point for a schedule discussion. Ask which hours a proposed candidate will cover and whether the service can support your part-time requirements.

The hiring model does not remove your team's scheduling work. Opus states: "The client chooses the finalist and manages day-to-day work." Your manager should therefore approve the working window before choosing the finalist.

Opus's pricing statement is: "Opus charges one flat monthly rate per hire. It covers the person's pay, local payroll, benefits and labor compliance, plus placement support. There is no separate recruiting fee. The rate depends on role, seniority and location." See the Opus pricing page.

Published dollar rates: Not published. Ask for a written quote tied to the proposed role and hours. Do not assume a reduced schedule produces a proportional reduction in price.

Bring the hiring manager's calendar to the conversation. Include the recurring coverage window, work that can happen independently and the person responsible for handoffs. Ask Opus to confirm the proposed arrangement before you compare candidates.

Keep that confirmation with the role description throughout the search. If interviews reveal that the work needs different hours, update the schedule and quote before choosing a finalist. Do not leave the candidate to resolve conflicting expectations after accepting.

The final schedule should be clear enough for both the manager and candidate to put into their calendars without another explanation. Confirm the local hours in both seasons, then use that agreement throughout interviews and onboarding.
