Questions

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

AEST is currently 30 minutes ahead of ACST. Add 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 9 * * 1-5 in AEST.

What is the time difference between ACST and AEST?

Australian Central Time is UTC+9:30 / UTC+10:30 and Australian Eastern Time is UTC+10 / UTC+11. Right now aEST is currently 30 minutes ahead of ACST.

Does daylight saving time affect ACST to AEST cron conversion?

ACST and AEST observe daylight saving time, so the difference between ACST (UTC+9:30 / UTC+10:30) and AEST (UTC+10 / UTC+11) 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 0 * * * in AEST.
