Scheduling across time zones is the kind of small task that quietly eats brain cycles. "What time is the Sydney call in New York and London?" is a calculation you do not want to do in your head, especially when daylight saving time shifts the answer twice a year in some regions.
The calculator takes a base time and zone, then displays the equivalent local time in any other zones you tick. The list covers the most common business hubs across Asia, Europe, the Americas, Australia and Africa.
Daylight saving is handled automatically using the runtime time zone data — if your source or target zone observes DST, the conversion accounts for whichever rule is currently in effect on the chosen date.
Yes — daylight saving rules are baked into the runtime time zone database (IANA). The conversion uses whichever rule applies on the chosen date.
Because of DST. Most US, European, Australian and South American zones shift by an hour twice a year. Asian and African zones generally do not.
Most cities follow a known regional zone (e.g., Tokyo uses Asia/Tokyo). Pick the closest match in the dropdown. To suggest a new zone, use the Contact page.
The Time Zone Converter lives alongside Age Calculator, Date Convert to Major Calendars, Date Count Calculator on the Productivity page. That landing page collects every productivity tool Dailiyo publishes, plus the editorial notes on formula sources, review cadence and how each result should (and should not) be interpreted.
