Questions

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

HST is currently 4 hours behind CST. Subtract 4 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 CST) becomes 0 5 * * 1-5 in HST.

What is the time difference between CST and HST?

Central Time is UTC-6 / UTC-5 and Hawaii Time is UTC-10. Right now hST is currently 4 hours behind CST.

Does daylight saving time affect CST to HST cron conversion?

CST observes daylight saving time, so the difference between CST (UTC-6 / UTC-5) and HST (UTC-10) changes during the year. Re-check your converted cron after each DST change.

What is midnight CST in HST cron?

Midnight in CST (0 0 * * *) is 0 20 * * * in HST, on the previous day.
