Questions

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

IST is currently 3 hours 30 minutes behind JST. Subtract 3 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 JST) becomes 30 5 * * 1-5 in IST.

What is the time difference between JST and IST?

Japan Standard Time is UTC+9 and India Standard Time is UTC+5:30. Right now iST is currently 3 hours 30 minutes behind JST.

Does daylight saving time affect JST to IST cron conversion?

Neither JST nor IST observes daylight saving time, so the 3 hours 30 minutes difference stays the same all year.

What is midnight JST in IST cron?

Midnight in JST (0 0 * * *) is 30 20 * * * in IST, on the previous day.
