How to Convert Time Zones Manually

  1. 1Find the UTC offset of the source city: e.g. New York (EST) = UTC−5
  2. 2Convert source time to UTC: e.g. 3:00 PM EST + 5 hours = 8:00 PM UTC
  3. 3Add the destination UTC offset: e.g. London (GMT) = UTC+0 → 8:00 PM UTC = 8:00 PM London
  4. 4Adjust for DST if applicable: During summer, New York is EDT (UTC−4) and London is BST (UTC+1)

Frequently Asked Questions

What is UTC?

UTC (Coordinated Universal Time) is the global time standard. All other time zones are expressed as offsets from UTC, e.g. New York is UTC−5 in winter and UTC−4 in summer.

How do I convert time zones?

Convert source time to UTC, then apply the destination offset. Example: 3 PM New York (UTC−5) → 8 PM UTC → 8 PM London (UTC+0).

What is Daylight Saving Time (DST)?

DST is the practice of advancing clocks by one hour during summer months to make better use of daylight. Not all countries observe DST — Japan, China, India, and most of Africa do not.

What is the best time for a global meeting?

For meetings covering New York, London, and Singapore: 9 AM EST = 2 PM London = 10 PM Singapore. This is often the best overlap window as all participants are within normal working hours or reasonable evening time.
