Questions

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

HST is currently 20 hours 30 minutes behind ACST. Subtract 20 hours 30 minutes to the hour and minute field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 ACST) becomes 30 12 * * 0-4 in HST.

What is the time difference between ACST and HST?

Australian Central Time is UTC+9:30 / UTC+10:30 and Hawaii Time is UTC-10. Right now hST is currently 20 hours 30 minutes behind ACST.

Does daylight saving time affect ACST to HST cron conversion?

ACST observes daylight saving time, so the difference between ACST (UTC+9:30 / UTC+10:30) and HST (UTC-10) changes during the year. Re-check your converted cron after each DST change.

What is midnight ACST in HST cron?

Midnight in ACST (0 0 * * *) is 30 3 * * * in HST, on the previous day.
