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.
