Questions

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

IST is currently 11 hours 30 minutes ahead of CST. Add 11 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 CST) becomes 30 20 * * 1-5 in IST.

What is the time difference between CST and IST?

Central Time is UTC-6 / UTC-5 and India Standard Time is UTC+5:30. Right now iST is currently 11 hours 30 minutes ahead of CST.

Does daylight saving time affect CST to IST cron conversion?

CST observes daylight saving time, so the difference between CST (UTC-6 / UTC-5) and IST (UTC+5:30) changes during the year. Re-check your converted cron after each DST change.

What is midnight CST in IST cron?

Midnight in CST (0 0 * * *) is 30 11 * * * in IST.
