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.
