Questions

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

AST is currently 14 hours 30 minutes behind ACST. Subtract 14 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 18 * * 0-4 in AST.

What is the time difference between ACST and AST?

Australian Central Time is UTC+9:30 / UTC+10:30 and Atlantic Time is UTC-4 / UTC-3. Right now aST is currently 14 hours 30 minutes behind ACST.

Does daylight saving time affect ACST to AST cron conversion?

ACST and AST observe daylight saving time, so the difference between ACST (UTC+9:30 / UTC+10:30) and AST (UTC-4 / UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight ACST in AST cron?

Midnight in ACST (0 0 * * *) is 30 9 * * * in AST, on the previous day.
