Questions

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

HST is currently 5 hours behind EST. Subtract 5 hours to the hour field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 EST) becomes 0 4 * * 1-5 in HST.

What is the time difference between EST and HST?

Eastern Time is UTC-5 / UTC-4 and Hawaii Time is UTC-10. Right now hST is currently 5 hours behind EST.

Does daylight saving time affect EST to HST cron conversion?

EST observes daylight saving time, so the difference between EST (UTC-5 / UTC-4) and HST (UTC-10) changes during the year. Re-check your converted cron after each DST change.

What is midnight EST in HST cron?

Midnight in EST (0 0 * * *) is 0 19 * * * in HST, on the previous day.
