Questions

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

EAT is currently 6 hours behind JST. Subtract 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 JST) becomes 0 3 * * 1-5 in EAT.

What is the time difference between JST and EAT?

Japan Standard Time is UTC+9 and East Africa Time is UTC+3. Right now eAT is currently 6 hours behind JST.

Does daylight saving time affect JST to EAT cron conversion?

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

What is midnight JST in EAT cron?

Midnight in JST (0 0 * * *) is 0 18 * * * in EAT, on the previous day.
