Nearshore time zone overlap: US hiring hours by country

What is the short answer for a busy buyer?

Choose a shared work window before choosing a hiring location. Write down when the manager and the people who approve the hire's work must be available. Then test that window against the candidate's city across seasonal clock changes.

Geographic proximity alone does not settle that question. A person can share your clock and work a different shift. Another can live ahead of you and accept a schedule that covers your busiest period.

Start with work that needs a live response. An engineer may need a reviewer during a release. A support hire may need to cover a defined queue. Ask when those tasks happen and who must be available.

Avoid copying the entire US office schedule into every role. Decide which hours the job needs, then ask whether the candidate can sustain them. An interview outside someone's usual workday does not establish their availability for a recurring shift.

Keep the accepted schedule with the role description. Recruiters can use it during screening, and managers can use it when choosing a finalist.

For a senior engineer, separate time spent writing code from time spent waiting for a decision. Ask which design reviews require a live discussion and which can happen through written comments. For an AI hire, identify who can review the work and when that person is free. The useful window depends on those people as well as the hire.

Write the requirement in terms a candidate can accept or decline. "Available for our daily review during the agreed shared window" is clearer than "flexible with US hours." If a recurring meeting is mandatory, include its time before interviews begin.

Also distinguish full-time work from full-day meeting availability. Give the hire time for tasks that need concentration within the accepted schedule. Before adding a daily meeting, decide which decision it will resolve and who needs to attend. A calendar filled with calls can leave little room to complete the work discussed on those calls.

What does the data say about LatAm overlap by US city?

The table compares workdays running from 9 a.m. to 5 p.m. in each person's city. Each cell shows shared hours during US standard time, followed by US daylight time.

The snapshots use January 15, 2027, and July 15, 2026. These are clock calculations before breaks or leave, based on IANA North American rules and South American rules.

All table values are calculated from the city offsets in the North American and South American time-zone rules. They describe matching local workdays, not a candidate's promised availability.

For a New York manager, Bogotá provides a close clock match. Chicago buyers should check how their relationship with Mexico City changes across US clock seasons. Pacific buyers should examine afternoon coverage before choosing a location.

Mexico City, Guadalajara, and Monterrey do not change clocks seasonally. Tijuana follows US daylight saving changes. Use the actual city rather than writing "Mexico time" in an offer. IANA North American rules.

Bogotá, Buenos Aires, and São Paulo do not change clocks seasonally. Their relationship to a US manager can still change when the manager's clock moves. IANA South American rules.

Santiago needs a date-specific check because Chile and the US change clocks on different dates. Do not apply a seasonal snapshot to every meeting throughout the year. IANA South American rules.

Set recurring meetings with named calendar zones. Then check whether each invitation falls inside the accepted workday. A calendar can convert a meeting correctly while placing it outside someone's shift.

Turn shared hours into a working schedule

Read a table cell as the maximum shared window under its stated assumptions. Lunch, existing meetings and time away from the desk can reduce the hours available for a live review. Put those commitments beside the proposed workday before calling the schedule a fit.

Check both ends of the window. A US manager may be free when the hire starts but busy when the hire needs approval. Ask the reviewer to reserve time before the hire finishes, especially when a blocked task would otherwise wait until the next day.

If your team spans several US cities, choose the calendar that governs the role. A hire who can attend the manager's meetings may still miss a product review run from another coast. Record those exceptions separately so the candidate sees the full requirement.

Do not use the Denver column for a manager based elsewhere without checking that location's clock rules. The table compares the named cities. Build the final offer around the actual people and their accepted hours.

For a practical check, put a proposed code review near the end of the shared window. Allow time for the reviewer to read the change and for the engineer to respond. If the review ends as the engineer signs off, decide where any follow-up work belongs. Moving the initial review earlier may solve the problem without changing either person's shift.

Check onboarding separately from the steady weekly schedule. The new hire may need help with access or a walkthrough from someone outside the usual review group. Book those sessions within the accepted hours before the start date. Give the hire a named contact for access problems so a missed setup step does not consume the next shared window.

How do the hiring models differ here?

Compare who screens for availability, records the accepted schedule, and handles later changes. The hiring model does not alter the clock relationship between cities.

Direct hiring

Put the expected schedule in the offer. Assign an internal owner for calendar questions and changes to working hours. Ask the appropriate local adviser to review the proposed terms before making commitments.

Make sure the hiring manager and the person preparing the offer use the same schedule. If one describes a local workday and the other describes US office hours, resolve that difference before the candidate signs.

A recruiting agency

Ask the agency to screen against the actual work window. "Comfortable with US hours" leaves too much room for different expectations.

Require the candidate's local schedule alongside the interview notes. Confirm who owns scheduling questions after placement.

Ask whether the shortlist includes candidates who accepted the recurring hours or candidates who merely agreed to an interview. Keep that distinction visible when comparing finalists. A strong interview does not resolve an unanswered schedule question.

An employer of record

Ask which schedule questions the employer of record handles and which remain with your manager. Confirm who reviews proposed changes and explains the applicable holiday arrangements.

Give the hire a clear contact for daily work questions. Avoid sending routine scheduling requests back and forth between payroll and the manager.

Before extending a workday or adding an on-call rotation, ask for a review of the proposed arrangement. Keep the written schedule consistent with what the manager asks the person to do.

A recruiting and placement partner

Ask which responsibilities continue after the person starts. Name the contact who will help if the accepted schedule and the manager's expectations diverge.

For Opus, the client chooses the finalist and manages day-to-day work.

Give each hiring option the same work window and meeting expectations. Otherwise, proposals may describe different schedules even when they all promise overlap.

Compare the proposed schedules before comparing fees. If one candidate accepts the required window and another needs meetings moved, that is a hiring decision for your team. Do not leave it for the new hire to resolve after starting.

What should you ask a provider?

Ask for a schedule you can place beside your team's calendar. It should name the candidate's city and show the local start and finish on both sides.

Which hours has the candidate accepted?

Confirm the recurring shift directly during the interview. Include breaks and any meetings that cannot move.

Show the candidate a normal workday. Explain when requests arrive and when reviewers respond. Let the person describe constraints before you choose a finalist.

Ask about the difference between regular availability and occasional flexibility. Someone may accept a rare late meeting without agreeing to a permanent evening shift. Keep those two expectations separate in the offer and in the manager's notes.

Also ask what happens if the manager changes teams or locations. The hire should know whether the agreed schedule stays in place until both sides discuss a change. Assign someone to resolve that question before it becomes a calendar dispute.

Keep the schedule in a place the hire and manager can both find. Include the effective date and the person who can approve a change. When someone proposes different hours, show the revised local workday before asking for agreement. Update recurring invitations only after the people involved understand what will change.

What changes when US clocks move?

Ask whether the hire keeps the same local schedule or follows the manager's clock changes. Record the answer and assign someone to check recurring meetings before the change.

Do not treat a calendar invitation as consent to a new shift. Discuss changes that move a meeting outside accepted hours.

Review the whole meeting series, including future dates. Check the hire's local start and finish against the manager's first and last required meetings. If a meeting no longer fits, decide whether to move it or discuss a schedule change.

How will holidays and leave affect delivery?

Ask which holiday calendar applies and how absences reach the team calendar. Confirm coverage before promising a release or customer deadline. Use the Opus LatAm holiday planner when reviewing dates.

Name an alternate approver for work that cannot wait. A team can have ample shared hours and still stall because the person who approves the work is away.

Review leave on both sides of the relationship. If the US manager is away while the hire is working, give the hire a task they can complete without that manager's approval. If the hire is away, move the handoff or assign coverage before the deadline.

What happens outside the shared window?

Separate routine messages from urgent incidents. State where each belongs and when the sender should expect a response.

Keep on-call duties separate from normal overlap. Ask the provider to explain the proposed arrangement before the candidate accepts it.

Agree on what a handoff needs to contain. For an engineering task, that could mean the current status, the blocked decision and a link to the work. The next person should be able to act without asking the same question again.

A message sent after the hire's workday should have a clear owner until that person returns. If the team expects immediate action, put that expectation into the schedule discussion.

Define how the sender signals urgency. A routine review request should not carry the same response expectation as an incident assigned to an on-call person. Put the expected response window in the team agreement and discuss examples during onboarding. This gives the hire a way to judge whether a message can wait until their next working period.

Can the team complete a real handoff?

Choose a normal task that needs approval. Walk through when it arrives, who reviews it, and what happens if a person finishes their shift before approval.

Use the manager's actual calendar. Protect a review slot rather than assuming every shared hour is free. Repeat the exercise for a deadline near the end of the US workday.

If the schedule fails that test, change the deadline, assign another reviewer, or discuss a different shift before sending the offer.

Repeat the check after the hire starts. Look at a blocked task and ask whether the cause was a missed handoff, an absent reviewer or a genuine gap in working hours. Fix the specific cause before asking the hire to extend their day.
