8:35 PM
PST
Time difference: -3 hours

How to Do It Manually

To convert between time zones manually, find the UTC offset for each zone and calculate the difference. Add or subtract hours accordingly.

Target Time = Source Time + (Target UTC Offset − Source UTC Offset)
  1. Look up the UTC offset for your source time zone (e.g. EST = UTC−5).
  2. Look up the UTC offset for your target time zone (e.g. CET = UTC+1).
  3. Subtract source offset from target offset to get the difference.
  4. Add that difference to your source time.
  5. Adjust for date changes if the result goes past midnight.
