Convert Time Between Time Zones
Convert any time between US, European, and Asian time zones. See current time in multiple cities.
Common Time Zone Conversions
Key offsets from EST: PST: -3 hours (9 AM EST = 6 AM PST). GMT/London: +5 hours (9 AM EST = 2 PM GMT). CET/Europe: +6 hours. IST/India: +10.5 hours. JST/Tokyo: +14 hours (9 AM EST = 11 PM JST). AEST/Sydney: +15 hours. These offsets change during daylight saving time transitions.
Scheduling Across Time Zones
For US coast-to-coast meetings: 12-2 PM EST (9-11 AM PST) works for both coasts during business hours. For US-Europe: 8-10 AM EST (1-3 PM GMT) is the overlap window. For US-Asia: there is almost no overlap during business hours — early morning US (7-8 AM EST) catches late afternoon Asia (8-9 PM JST).
The most common meeting scheduling mistake: forgetting that India is +10.5 hours (not +10) and that Australia has three time zones with 30-minute offsets. Use tools like World Time Buddy or Every Time Zone to visualize overlap windows — they prevent embarrassing scheduling errors.
