Questions

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

MST is currently 16 hours behind JST. Subtract 16 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 JST) becomes 0 17 * * 0-4 in MST.

What is the time difference between JST and MST?

Japan Standard Time is UTC+9 and Mountain Time is UTC-7 / UTC-6. Right now mST is currently 16 hours behind JST.

Does daylight saving time affect JST to MST cron conversion?

MST observes daylight saving time, so the difference between JST (UTC+9) and MST (UTC-7 / UTC-6) changes during the year. Re-check your converted cron after each DST change.

What is midnight JST in MST cron?

Midnight in JST (0 0 * * *) is 0 8 * * * in MST, on the previous day.
