Time zone converter

How it works

You enter the wall-clock time in your base zone. We resolve that to a single instant in time, then format that instant in every other zone you've added. Daylight saving transitions are handled by the browser's built-in Intl.DateTimeFormat, so spring-forward and fall-back edge cases are correct.

Tips for scheduling

• Put the meeting in the most-distant attendee's zone first — it makes "is this still tomorrow?" obvious to everyone else.
• For weekly recurring meetings, double-check the week before each DST transition. Most calendar apps handle it, but human-entered local times don't.
