Questions

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

EST is currently 14 hours behind JST. Subtract 14 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 19 * * 0-4 in EST.

What is the time difference between JST and EST?

Japan Standard Time is UTC+9 and Eastern Time is UTC-5 / UTC-4. Right now eST is currently 14 hours behind JST.

Does daylight saving time affect JST to EST cron conversion?

EST observes daylight saving time, so the difference between JST (UTC+9) and EST (UTC-5 / UTC-4) changes during the year. Re-check your converted cron after each DST change.

What is midnight JST in EST cron?

Midnight in JST (0 0 * * *) is 0 10 * * * in EST, on the previous day.
