What is UTC and why is it used?

UTC (Coordinated Universal Time) is the global time standard — all time zones are defined as UTC + or − hours. Using UTC for scheduled tasks, server logs, and database timestamps avoids daylight saving complications.

How does Daylight Saving Time affect scheduling?

DST shifts clocks by 1 hour in spring and back in autumn. Not all countries observe DST — UAE, India, China, and Japan do not. Between March and November, Europe and North America are 1 hour closer than in winter. Use city names (not offset) for automatic DST handling.

What are good meeting times for UK, US, and Bangladesh?

Xgenious example: UK (GMT), US Eastern (GMT-5), Bangladesh (GMT+6). Best overlap: 2–4pm UK time = 9–11am ET = 8–10pm Bangladesh. The Bangladesh workweek is Sunday–Thursday, so Friday/Saturday meetings are outside standard hours.

How should distributed teams handle async vs sync communication?

Default to async (Slack, Loom, email) for all non-urgent communication. Reserve synchronous meetings for decisions requiring real-time discussion. GitLab (1,500+ fully remote employees) targets fewer than 2 synchronous hours per week per person.

How do I find a meeting time that works across time zones?

List every participant's time zone and working hours, then look for the hours of the day that fall inside everyone's working window at once. This planner shows all time zones on one 24-hour grid and highlights the overlapping hours automatically.

How do I handle recurring meetings across time zones when DST changes?

Schedule recurring meetings using city-based time zone references, not UTC offsets. "9am London time every Monday" adjusts automatically when UK clocks change. Verify the series in both summer and winter when first setting it up — the Outlook/Google Calendar meeting will adjust, but attendees may not notice the offset shift.

Is my data sent to a server?

No. Time zone calculations run entirely in your browser using the IANA time zone database bundled with the tool. Your selected locations, working hours, and meeting preferences are never transmitted to any server or stored.

Features

Everything you need in one Time Zone Meeting Planner

All time zones at once

See the full 24-hour day for every location side by side, so the workable hours are obvious instead of guessed.

Best-overlap finder

The planner scans every hour and highlights the window where the most participants are within working hours.

Per-location working hours

Set different working hours for each location — a 9-to-5 office and a flexible remote worker are not the same.

Daylight-saving accurate

Built on the browser's time zone engine, so it reflects each region's current daylight-saving state automatically.

How It Works

Set working hours per location

Adjust the standard working hours (default 9am–6pm) for each location if needed.

Using fixed UTC offset instead of city nameUTC+6 scheduled for all year — misses Bangladesh daylight periods

Always select city names (Dhaka, London, New York) not UTC±N offsets. City names trigger correct DST handling automatically.

Forgetting Bangladesh Sunday–Thursday workweekRecurring Friday meeting includes Bangladesh team member

Bangladesh workweek is Sunday–Thursday. Friday and Saturday are weekends. Set any recurring Friday/Saturday meetings to Thursday alternative for BD participants.

Booking recurring meetings in summer without checking winter offsetUS/UK team meeting works in July but clashes by 1 hour in January

DST in UK ends last Sunday in October. US ends first Sunday in November. There is a 1-week window where clocks diverge — verify recurring meetings span both seasons.

Treating "available" as any non-sleeping hourMeeting at 8pm local time counts as overlap for participant

Distinguish working hours (9am–6pm), commute hours, and hard stops. Respect cultural lunch breaks — 1pm–2pm in UK/EU, 2pm–3pm in BD.

Ignoring national holidays when finding "available" slotsScheduling a meeting on Eid Al-Fitr for the Bangladesh team

Cross-reference national holidays for each participant's country. A time that falls in "working hours" on a public holiday is still unavailable.

Assuming India observes DSTAdjusting India time +1 in summer "for DST"

India Standard Time (IST, UTC+5:30) does not change for DST — it is constant year-round. Same for UAE (UTC+4), China (UTC+8), Japan (UTC+9), and Singapore (UTC+8).

FAQ

Frequently asked questions

Most common for SaaS companies: US Eastern (ET), US Pacific (PT), UK/GMT, Central European (CET), India (IST), Singapore (SGT), and UAE (GST). Finding overlap between ET and IST is the hardest — a 5:30am ET start is 4pm IST, making 8–9am ET to 10:30am ET the best overlap window.
