Questions

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

JST is currently 19 hours ahead of HST. Add 19 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 HST) becomes 0 4 * * 2-6 in JST.

What is the time difference between HST and JST?

Hawaii Time is UTC-10 and Japan Standard Time is UTC+9. Right now jST is currently 19 hours ahead of HST.

Does daylight saving time affect HST to JST cron conversion?

Neither HST nor JST observes daylight saving time, so the 19 hours difference stays the same all year.

What is midnight HST in JST cron?

Midnight in HST (0 0 * * *) is 0 19 * * * in JST.
