Questions

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

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

What is the time difference between ACST and IST?

Australian Central Time is UTC+9:30 / UTC+10:30 and India Standard Time is UTC+5:30. Right now iST is currently 5 hours behind ACST.

Does daylight saving time affect ACST to IST cron conversion?

ACST observes daylight saving time, so the difference between ACST (UTC+9:30 / UTC+10:30) and IST (UTC+5:30) changes during the year. Re-check your converted cron after each DST change.

What is midnight ACST in IST cron?

Midnight in ACST (0 0 * * *) is 0 19 * * * in IST, on the previous day.
