Questions

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

CST is currently 11 hours 30 minutes behind IST. Subtract 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 IST) becomes 30 21 * * 0-4 in CST.

What is the time difference between IST and CST?

India Standard Time is UTC+5:30 and Central Time is UTC-6 / UTC-5. Right now cST is currently 11 hours 30 minutes behind IST.

Does daylight saving time affect IST to CST cron conversion?

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