Questions

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

HST is currently 21 hours behind AEST. Subtract 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 AEST) becomes 0 12 * * 0-4 in HST.

What is the time difference between AEST and HST?

Australian Eastern Time is UTC+10 / UTC+11 and Hawaii Time is UTC-10. Right now hST is currently 21 hours behind AEST.

Does daylight saving time affect AEST to HST cron conversion?

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

What is midnight AEST in HST cron?

Midnight in AEST (0 0 * * *) is 0 3 * * * in HST, on the previous day.
