Frequently asked questions
What is the time difference between BST and JST?+
BST is UTC+01:00 and JST is UTC+09:00 in standard time. The gap between them changes during the year if either place observes daylight saving, so enter a date to see the difference on that day.
Does BST observe daylight saving time?+
No. BST stays on UTC+01:00 all year.
Does JST observe daylight saving time?+
No. JST stays on UTC+09:00 all year.
Why does one local time sometimes have two answers?+
When clocks go back, the hour before the change repeats, so that local reading happens twice and both instants are valid. When clocks go forward, the skipped hour never occurs, so that reading has no matching instant at all. The converter reports both cases rather than guessing.
