Time zone converter and meeting planner
Choose a date and time in one place, add the cities you work with, and see what time it is for everyone. Set each person's working hours and the planner shows the window where all of you are available. It all runs in your browser.
1. Pick a date and time
That is a normal local time in UTC; there is only one moment it can mean.
2. Add places to compare
Add up to 8 places. Type a city name in English or Chinese, or an IANA time zone name.

3. Find a meeting time that suits everyone
Set the hours people can take a meeting in each place. Green shows when everyone is inside their hours.
An end earlier than the start (such as 22:00 to 06:00) means the hours run past midnight.
Common window
There is no time on this UTC day when everyone is inside their hours. Try widening the hours or checking the next day.

Everyone
- Inside working hours
- Everyone available
- Your chosen time
Each bar covers the UTC calendar day of the date you picked, midnight to midnight. The times above the bars are UTC time.
How it works
- •You pick a local date and time in one place. The converter turns it into a single moment in time, then shows that same moment on the clock in each place you add, with the date, weekday, UTC offset and whether it falls on another day.
- •Offsets come from the time zone data built into your browser, so daylight saving rules, half-hour zones such as India and 45-minute zones such as Nepal are handled the way your device handles them. Very recent or future rule changes depend on how up to date your browser is.
- •A local time can be skipped when clocks jump forward or happen twice when they go back. The page tells you when that happens and lets you choose the offset from before or after the clock change; by default it uses the one from before.
- •For the meeting planner, each bar covers one calendar day in the place you chose, midnight to midnight. A minute counts as available in a place when that place's own clock reads inside its working hours, and the green part is where every place is available at once.
Questions
- How do I convert a time from one time zone to another?
- Pick the date and time, choose the place it is in, and add the other places in the search box. Each card shows what the clock reads there at that same moment, and a note tells you if it is already the next day or still the previous one.
- What happens to times that do not exist or happen twice because of daylight saving?
- When clocks jump forward, some local times are skipped; when they go back, some happen twice. The page says which case you are in, shows the offset it used, and lets you switch between the offset from before and the one from after the change.
- How does the meeting planner decide when everyone is available?
- You set working hours for each place, 09:00 to 17:00 by default. A minute is counted for a place when its local clock is inside those hours, and the common window is where every place counts at the same time. If you enter an end earlier than the start, such as 22:00 to 06:00, the hours run past midnight. If there is no overlap the page says so.
- Is my information sent anywhere?
- No. The conversion uses your browser's own time zone data and nothing you enter is sent, saved or stored. If you reload the page it starts again.
