Questions

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

AEST is currently 30 minutes behind ACST. Subtract 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 8 * * 1-5 in AEST.

What is the time difference between ACST and AEST?

Australian Central Time is UTC+9:30 / UTC+10:30 and Brisbane Time (Queensland) is UTC+10. Right now aEST is currently 30 minutes behind ACST.

Does daylight saving time affect ACST to AEST cron conversion?

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

What is midnight ACST in AEST cron?

Midnight in ACST (0 0 * * *) is 30 23 * * * in AEST, on the previous day.
