About Time.bi
Time.bi answers one question quickly, for anywhere on Earth: what time is it there, and what does that mean for you right now? It covers 249 countries, more than 8,300 cities and 3,838 states, provinces and regions, with every clock running live.
Time in every city and country
Each city has its own page with the current time, date and time zone. Tokyo is a good example: alongside the clock you get sunrise and sunset, moon phases and the weather for the same city.
To look further, browse all countries, all cities or states and regions. Country pages such as Japan show every time zone a country uses and the main cities in each.
Time zones, explained
Time.bi follows the IANA time zone database, the reference that phones and computers use. You can browse:
- Time zone groups such as EST, CET or IST, with the zones inside each one
- All 596 IANA time zones, from Africa/Abidjan to Pacific/Wallis
- UTC, the reference clock behind all of them, and the military time zones from Alpha to Zulu
- A time zone map of the whole world
Tools for working across time zones
- World clock: several cities side by side
- Time zone converter: turn a time in one place into the time in another
- Meeting planner: find an hour that works for people in different countries
- Event planner: share one event time that each guest sees in their own zone
- Time calculator: work out a date or time a number of days or hours ago, or from now
- Unix time: the current Unix timestamp, live
Sun, moon and weather
Sunrise times and sunset times are calculated from each city's coordinates, day by day, together with day length and twilight. City pages add moonrise, moonset and the moon's phase, and the weather section covers current conditions and forecasts.
Dates, holidays and countdowns
- Public holidays by country, including regional holidays and days observed in lieu
- Calendars by year and month, with public holidays marked for the US, UK and Canada
- Week numbers using the ISO standard
- Countdowns to holidays and events around the world
Timers and clocks
Use the timer, multi-timer, alarm clock or stopwatch in the browser, with nothing to install. If you run a website, the free clock widgets put a live clock on your own pages.
Articles
The Time.bi blog explains how time works in practice, from why some time zones are 30 or 45 minutes off the hour to why the earliest sunrise does not fall on the longest day.
