Questions

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

JST is currently 8 hours ahead of CET. Add 8 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 CET) becomes 0 17 * * 1-5 in JST.

What is the time difference between CET and JST?

Central European Time is UTC+1 / UTC+2 and Japan Standard Time is UTC+9. Right now jST is currently 8 hours ahead of CET.

Does daylight saving time affect CET to JST cron conversion?

CET observes daylight saving time, so the difference between CET (UTC+1 / UTC+2) and JST (UTC+9) changes during the year. Re-check your converted cron after each DST change.

What is midnight CET in JST cron?

Midnight in CET (0 0 * * *) is 0 8 * * * in JST.
