Time Zone Converter
Convert a specific date and time to multiple time zones at once. Built on the same accurate offset logic as our Timezone Meeting Finder, with DST handled automatically.
Offsets are calculated for the selected date, so daylight saving changes are respected.

What is a Time Zone Converter?
A time zone converter shows what a specific date and time looks like in other regions. Instead of manually calculating offsets or remembering daylight saving rules, you set the source time and see equivalent times everywhere else instantly.
This tool shares the same timezone database and daylight saving handling as our Timezone Meeting Finder, but streamlined for quick one-to-many conversions. It is ideal for scheduling webinars, customer calls, or launches where you need to publish the same moment in many time zones.
How this converter works
1) Pick your source
Set the exact date, time, and time zone you care about. The converter uses the selected date when determining offsets, so future daylight saving changes are honored.
2) Add destinations
Add multiple target time zones, or tap the quick-add shortcuts for common regions. Remove or reset targets at any time.
3) Copy & share
Copy the formatted results and paste them into emails, calendars, or product launch announcements.
Tips for scheduling across zones
Use local-friendly times
Avoid 6 AM and midnight slots where possible.
Call out the zone
Always include the time zone when sharing times.
Double-check DST
DST shifts differ by country—re-run conversions near switch dates.
Share multiple views
Include two or three key regions (e.g., UTC, US, Europe) to reduce confusion.
Publishing checklist
- Confirm the source date/time and the correct home timezone.
- Add a UTC anchor plus 2–4 key audience regions (e.g., New York, London, Singapore, Sydney).
- Use the exact event date to ensure DST is applied correctly.
- Generate the copy block and paste it into the invite, doc, or landing page.
- Scan for AM/PM ambiguity; prefer 24-hour time when possible.
- Double-check that recurring events list the right offsets on future dates.

DST pitfalls to avoid
Different switch dates
The US, UK, EU, and APAC shift on different weekends. Always set the exact event date in the converter.
Regions without DST
Places like Singapore or Arizona do not shift; rely on the converter offsets instead of assumptions.
Southern hemisphere
Summer/winter are inverted; expect October/November changes. Use the date picker to stay accurate.
Recurring events
Offsets can differ after a DST change. Re-run conversions for future occurrences to avoid surprises.
