How it works
This meeting planner lets you pick a time of day and instantly see what that moment corresponds to in major cities around the world. It is designed for teams spread across multiple timezones who need to find a slot that falls within working hours for everyone involved.
Select a date and a time in your reference timezone, and the grid updates to show the equivalent local time in each listed city. Working-hours blocks (typically 09:00-18:00 local) are highlighted in green so you can scan for overlap at a glance. Early morning or late-night hours appear in red as a warning.
The tool accounts for Daylight Saving Time automatically, so the offsets adjust correctly for summer and winter dates. This matters especially for scheduling recurring meetings: a slot that works in November may shift by one hour for participants in regions that observe DST differently.
Use it before sending a calendar invite to confirm that your proposed time is reasonable for all attendees, or to find the least-bad option when participants are spread across Asia, Europe, and the Americas.
Worked example
Find a working-hours slot for a US-UK-India call
- Set your reference city to New York and the time to 9:00 AM.
- Check the grid: London shows 14:00 (fine), Mumbai shows 18:30 (end of day).
- Slide the time to 8:00 AM New York: London 13:00, Mumbai 17:30 — all within working hours.
- Send a calendar invite for 8:00 AM ET.
8:00 AM New York / 13:00 London / 17:30 Mumbai is the best overlap for all three offices.
Common mistakes to avoid
- Scheduling based on current offsets without checking whether the meeting date falls during a DST transition week.
- Ignoring that some countries (e.g. China, India, Japan) do not observe DST, while neighbouring regions do.
- Using the planner for a past date and forgetting to update the reference timezone if you have since traveled.
Key terms
- UTC Offset
- The number of hours (and sometimes half-hours) a timezone is ahead of or behind Coordinated Universal Time. For example, IST is UTC+5:30.
- Daylight Saving Time (DST)
- The practice of advancing clocks by one hour during summer months, observed in many but not all countries, which shifts a timezone's UTC offset seasonally.
- Working hours window
- Typically 09:00-18:00 local time, used by the planner to highlight acceptable meeting slots in green.
Frequently asked questions
- What does ✅ mean in the meeting planner?
- A green tick means the time falls within typical business hours (8 AM–8 PM) in that city. A warning means it is early morning or late evening.
