Frequently asked questions

What is the time difference between IST and SGT?+

IST is UTC+05:30 and SGT is UTC+08:00 in standard time. The gap between them changes during the year if either place observes daylight saving, so enter a date to see the difference on that day.

Does IST observe daylight saving time?+

No. IST stays on UTC+05:30 all year.

Does SGT observe daylight saving time?+

No. SGT stays on UTC+08:00 all year.

Why does one local time sometimes have two answers?+

When clocks go back, the hour before the change repeats, so that local reading happens twice and both instants are valid. When clocks go forward, the skipped hour never occurs, so that reading has no matching instant at all. The converter reports both cases rather than guessing.
