Time zone converter

How to use the converter

Pick the day, type a time in any row, and every other zone updates instantly. The row you typed in becomes the pivot. Add more cities with the "Add zone" button. When you find a time that works, hit "Copy share link" — your teammates open the same view.

Why we built it this way

Old converters force you to pick a "from" and a "to" zone, type the source time, then stare at one output. Real scheduling involves three or four cities, and you want to nudge each one to see what the other side looks like. Zeitful's converter lets every row be an input — adjust freely until you spot the overlap.

Best uses

• Confirming a meeting time across remote teammates before sending the invite.
• Setting a launch announcement to land at 9 a.m. in the biggest customer market.
• Helping family abroad understand when a call would actually be polite — check whether the other side is in business hours.
• Catching DST cliffs: switch the date by a day to see the offset move and avoid the dreaded "Spring forward miss".

Built on the IANA tzdata, so DST rules are correct for every city and every year. If you need a live world clock rather than a snapshot, the homepage shows ticking clocks for any set of cities.
