Questions

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

JST is currently 6 hours ahead of EAT. Add 6 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 EAT) becomes 0 15 * * 1-5 in JST.

What is the time difference between EAT and JST?

East Africa Time is UTC+3 and Japan Standard Time is UTC+9. Right now jST is currently 6 hours ahead of EAT.

Does daylight saving time affect EAT to JST cron conversion?

Neither EAT nor JST observes daylight saving time, so the 6 hours difference stays the same all year.

What is midnight EAT in JST cron?

Midnight in EAT (0 0 * * *) is 0 6 * * * in JST.
