Questions

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

IST is currently 15 hours 30 minutes ahead of HST. Add 15 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 HST) becomes 30 0 * * 2-6 in IST.

What is the time difference between HST and IST?

Hawaii Time is UTC-10 and India Standard Time is UTC+5:30. Right now iST is currently 15 hours 30 minutes ahead of HST.

Does daylight saving time affect HST to IST cron conversion?

Neither HST nor IST observes daylight saving time, so the 15 hours 30 minutes difference stays the same all year.

What is midnight HST in IST cron?

Midnight in HST (0 0 * * *) is 30 15 * * * in IST.
