Questions

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

JST is currently 9 hours ahead of WET. Add 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 WET) becomes 0 18 * * 1-5 in JST.

What is the time difference between WET and JST?

Western European Time is UTC+0 / UTC+1 and Japan Standard Time is UTC+9. Right now jST is currently 9 hours ahead of WET.

Does daylight saving time affect WET to JST cron conversion?

WET observes daylight saving time, so the difference between WET (UTC+0 / UTC+1) and JST (UTC+9) changes during the year. Re-check your converted cron after each DST change.

What is midnight WET in JST cron?

Midnight in WET (0 0 * * *) is 0 9 * * * in JST.
