Step by step
- Find the time difference: GMT is +5 hours relative to EST (January).
- Add or subtract that many hours from the EST time.
- Check daylight saving: in July the difference is +4 hours.
- If the result passes midnight, the date changes too.

How it works
Time zones are offsets from Coordinated Universal Time (UTC). Many people say “EST” or “PST” all year, but strictly EST and PST are standard time; during US daylight saving time (second Sunday in March to first Sunday in November) clocks use EDT and PDT. Countries such as Pakistan, India and Japan do not use daylight saving time, so their difference from US time changes twice a year. The converter above uses the official time zone database, so it is correct for any date.
