Questions

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

SAST is currently 8 hours 30 minutes behind ACST. Subtract 8 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 0 * * 1-5 in SAST.

What is the time difference between ACST and SAST?

Australian Central Time is UTC+9:30 / UTC+10:30 and South Africa Standard Time is UTC+2. Right now sAST is currently 8 hours 30 minutes behind ACST.

Does daylight saving time affect ACST to SAST cron conversion?

ACST observes daylight saving time, so the difference between ACST (UTC+9:30 / UTC+10:30) and SAST (UTC+2) changes during the year. Re-check your converted cron after each DST change.

What is midnight ACST in SAST cron?

Midnight in ACST (0 0 * * *) is 30 15 * * * in SAST, on the previous day.
