Questions

How do I convert a cron expression from JST to UTC?

UTC is currently 9 hours behind JST. Subtract 9 hours to the hour field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 JST) becomes 0 0 * * 1-5 in UTC.

What is the time difference between JST and UTC?

Japan Standard Time is UTC+9 and Coordinated Universal Time is UTC+0. Right now uTC is currently 9 hours behind JST.

Does daylight saving time affect JST to UTC cron conversion?

Neither JST nor UTC observes daylight saving time, so the 9 hours difference stays the same all year.

What is midnight JST in UTC cron?

Midnight in JST (0 0 * * *) is 0 15 * * * in UTC, on the previous day.
