Questions

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

HST is currently 20 hours behind AEST. Subtract 20 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 AEST) becomes 0 13 * * 0-4 in HST.

What is the time difference between AEST and HST?

Brisbane Time (Queensland) is UTC+10 and Hawaii Time is UTC-10. Right now hST is currently 20 hours behind AEST.

Does daylight saving time affect AEST to HST cron conversion?

Neither AEST nor HST observes daylight saving time, so the 20 hours difference stays the same all year.

What is midnight AEST in HST cron?

Midnight in AEST (0 0 * * *) is 0 4 * * * in HST, on the previous day.
