Questions

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

HST is currently 19 hours behind JST. Subtract 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 JST) becomes 0 14 * * 0-4 in HST.

What is the time difference between JST and HST?

Japan Standard Time is UTC+9 and Hawaii Time is UTC-10. Right now hST is currently 19 hours behind JST.

Does daylight saving time affect JST to HST cron conversion?

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

What is midnight JST in HST cron?

Midnight in JST (0 0 * * *) is 0 5 * * * in HST, on the previous day.
