Questions

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

AEST is currently 21 hours ahead of HST. Add 21 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 6 * * 2-6 in AEST.

What is the time difference between HST and AEST?

Hawaii Time is UTC-10 and Australian Eastern Time is UTC+10 / UTC+11. Right now aEST is currently 21 hours ahead of HST.

Does daylight saving time affect HST to AEST cron conversion?

AEST observes daylight saving time, so the difference between HST (UTC-10) and AEST (UTC+10 / UTC+11) changes during the year. Re-check your converted cron after each DST change.

What is midnight HST in AEST cron?

Midnight in HST (0 0 * * *) is 0 21 * * * in AEST.
