- Enter the time in the source zone.

- Read the converted time, plus whether it falls on the next or previous day.
Formula / logic
Converted time = Input time + (Target zone offset − Source zone offset), adjusted for a possible day change.
Worked example
3:00 PM EST converted to PST: PST is 3 hours behind EST, so the result is 12:00 PM PST.
Frequently asked questions
How many hours behind is PST from EST?
Pacific Standard Time is 3 hours behind Eastern Standard Time.
Does this tool adjust for daylight saving time automatically?
It uses standard zone offsets; double-check against the specific date if your event falls near a daylight saving changeover, since some zones shift by an hour part of the year.
What does it mean if the result shows 'next day'?
It means the converted time falls after midnight in the target zone — for example, 11:00 PM EST converted to a zone further east may land in the early hours of the following day.
