The top of the page shows the current date and time in Diego Garcia, ticking in the Indian/Chagos zone. To convert a specific moment to another city, use the comparison link below, where you can enter a date and time.
How the time is calculated
Diego Garcia is bound to the IANA identifier Indian/Chagos. The server resolves the UTC offset and daylight saving state for the requested moment and renders the first view; the browser then keeps time in the same zone and re-syncs when the tab comes back to the foreground. No fixed offset stands in for the zone, and no zone is guessed from the city name.
FAQ
- Which time zone is Diego Garcia in?
- Diego Garcia uses the IANA identifier Indian/Chagos, currently UTC+06:00. The same identifier can have different offsets on different dates; the value above is for the current moment.
- Does Diego Garcia observe daylight saving time?
- The daylight saving section above answers this from the IANA database: cities that do not observe it show no changeover text, and cities that do show the current state and the next local changeover time.
- How many hours is Diego Garcia from London?
- Calculated for the current moment: Diego Garcia is 5 hours ahead of London. The section above also shows each side’s local date at that same instant. Because the two places start and end daylight saving on different dates, the gap changes during the year — use the fixed-date mode in the comparison tool for another date.
- Can a cached page show the wrong time?
- No. The first render uses server time as a starting value, and as soon as the page loads the browser recomputes the current moment for Indian/Chagos and takes over the clock, so a cache hit still shows the time at which you opened it.
