How to use this tool
World clock
Fifteen major cities are shown to start. Type a city name and choose it from the suggestions to add it, or press × on a card to remove it. Each card shows the city's date, its time zone abbreviation and its current offset from UTC, with a day or night label based on local hours (06:00–17:59 is day).
Time zone converter
Choose two cities and a date and time, and the result shows both local times side by side, the UTC offsets, how far apart the cities are and whether the result falls on the previous day, the same day or the next day. Use Swap to reverse the direction.
Meeting planner
Set the meeting time in one city and add the cities of the other attendees. Each row is tagged as working hours, early or evening, or overnight, and the planner suggests whole-hour start times that put the most cities inside working hours.
Why daylight saving matters
The gap between two cities is not always the same number of hours. New York and London are normally five hours apart, but for a few weeks in spring and autumn the two countries change their clocks on different dates and the gap becomes four hours. Southern-hemisphere cities such as Sydney and Auckland move their clocks in the opposite season. Because this tool looks up the rules for the exact date you choose, rather than using one fixed offset per city, it follows those changes.
Two situations catch people out. When clocks jump forward, a local time such as 02:30 on that night never happens. When clocks go back, a time such as 01:30 happens twice. The converter warns you in both cases and shows which time it used.
Frequently asked questions
- How does the converter handle daylight saving time?
- It uses your browser's built-in IANA time zone database, so each city follows its own rules for the date you choose. Results are only as current as your browser's time zone data, so keep your browser updated.
- What happens if I pick a time that does not exist?
- When clocks jump forward, some local times are skipped. The tool tells you and uses the first valid time after the gap.
- What if a local time happens twice?
- When clocks go back, one local hour repeats. A selector lets you choose the earlier or the later occurrence.
- Why can the same moment be on different dates in different cities?
- Offsets range from UTC−12 to UTC+14, so at any instant places can be on different calendar days. Results are labelled previous day, same day or next day.
- Is my data sent anywhere?
- No. Everything runs in your browser. Your chosen cities and the 12-hour setting are stored only in your browser's local storage.
- What hours count as working hours?
- 09:00–16:59 is working hours, 07:00–08:59 and 17:00–21:59 is early or evening, and 22:00–06:59 is overnight. Your organisation's hours may differ.
