Questions

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

GMT is currently 5 hours 30 minutes behind IST. Subtract 5 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 3 * * 1-5 in GMT.

What is the time difference between IST and GMT?

India Standard Time is UTC+5:30 and Greenwich Mean Time (UK) is UTC+0 / UTC+1. Right now gMT is currently 5 hours 30 minutes behind IST.

Does daylight saving time affect IST to GMT cron conversion?

GMT observes daylight saving time, so the difference between IST (UTC+5:30) and GMT (UTC+0 / UTC+1) changes during the year. Re-check your converted cron after each DST change.

What is midnight IST in GMT cron?

Midnight in IST (0 0 * * *) is 30 18 * * * in GMT, on the previous day.
