Frequently asked questions
How many hours ahead is London of Tokyo?
It depends on the season. Around July London is 8 hours behind Tokyo; around January it is 9 hours behind Tokyo. The switch happens when one of the two moves to or from daylight saving time.
What time is 12:00 noon GMT in JST?
12:00 noon GMT is 20:00 JST.
Does GMT or JST use daylight saving time?
GMT observes daylight saving; JST does not. The difference between them therefore changes twice a year.
