Note: times are computed with fixed UTC offsets (standard time) and do not account for daylight saving time; verify DST status before scheduling real meetings.

FAQ
Does the tool account for daylight saving time?
No. All times use fixed UTC offsets (standard time). Verify whether DST is in effect at the destination and adjust by one hour if needed.
What counts as working hours?
9:00-18:00. Cities within that window are shown in green in the table, and the common working hours search uses the same range.
Which time zones are supported?
23 cities covering East Asia (Beijing, Tokyo, Seoul...), Europe (London, Paris, Moscow...), North America (New York, LA, Toronto...), the Middle East (Dubai), South Asia (Mumbai) and South America (Sao Paulo).
Why do some cities show previous/next day?
With time differences beyond half a day, some cities land on the adjacent calendar date; the tool tags it and shows the right weekday.
Can I convert precise minutes?
Yes. The time field accepts minutes (e.g. 09:30) and results are accurate to the minute.
