Quick guide
What can Time Zone Converter help you do?
Free time zone converter with global city quick-select and cross-timezone meeting planner. Auto-handles daylight saving.
Best for
Convert time between listed cities or plan a cross-region call. Compare Cities marks 08:00–18:00 work hours; a fixed UTC offset cannot predict DST.
How to use it
Choose Source Zone and Source Time, or use Current Time. Tick Compare Cities; table shows dates and Meeting Planner marks work, sleep, and overlap.
How to read the result
Results may use another date. A skipped DST time like 02:30 is rejected; equal UTC offsets can follow different rules.
Privacy and limits
Times stay in the browser and are not uploaded. Selected cities use localStorage; no attendee details are stored.
Check the meeting date. DST weeks or old time-zone data can alter results; ask attendees to confirm local time.
Frequently Asked Questions
Does it handle daylight saving (DST)?
Yes. We use the browser's built-in IANA time zone database (Intl.DateTimeFormat), which auto-handles DST transitions worldwide.
Why do some time zones have odd offsets?
Some regions use non-integer-hour offsets (e.g. India +5:30, Nepal +5:45). We display these accurately, not rounded.
How does the meeting planner work?
Add all participants' cities; the tool highlights when everyone is in business hours (8:00–18:00). No more 3 AM meetings.
Can I save favorite cities?
Yes, your selected cities are saved in browser localStorage and restored on next visit.
Which East Asian countries use DST?
None, currently. China, Taiwan, Japan, South Korea, Singapore, and Hong Kong have all abolished DST.
