Frequently asked questions
What is the time difference between EST and PST?▾
Pacific Time is 3 hours behind Eastern Time all year, because both switch to daylight saving on the same dates. 12:00 PM ET is 9:00 AM PT.
Does the converter handle daylight saving time?▾
Yes. It uses your browser's built-in time zone database (IANA), so offsets change automatically on the correct dates for every country — for example London is UTC+0 in winter and UTC+1 (BST) in summer.
What is the difference between UTC and GMT?▾
For everyday use they are the same time. GMT is also the name of the UK's winter time zone, while UTC is the international time standard that does not change with seasons.
What time is 9 AM EST in India?▾
India Standard Time is UTC+5:30 with no daylight saving. 9:00 AM EST (winter) is 7:30 PM IST; 9:00 AM EDT (summer) is 6:30 PM IST.
How do I find a good meeting time across time zones?▾
Enter a proposed time and look at the business-hours marker on each row. Rows marked ● fall between 9 AM and 5 PM on a weekday for that city.
