Questions

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

HST is currently 15 hours 30 minutes behind IST. Subtract 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 IST) becomes 30 17 * * 0-4 in HST.

What is the time difference between IST and HST?

India Standard Time is UTC+5:30 and Hawaii Time is UTC-10. Right now hST is currently 15 hours 30 minutes behind IST.

Does daylight saving time affect IST to HST cron conversion?

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

What is midnight IST in HST cron?

Midnight in IST (0 0 * * *) is 30 8 * * * in HST, on the previous day.
