Questions

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

JST is currently 12 hours ahead of ART. Add 12 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 ART) becomes 0 21 * * 1-5 in JST.

What is the time difference between ART and JST?

Argentina Time is UTC-3 and Japan Standard Time is UTC+9. Right now jST is currently 12 hours ahead of ART.

Does daylight saving time affect ART to JST cron conversion?

Neither ART nor JST observes daylight saving time, so the 12 hours difference stays the same all year.

What is midnight ART in JST cron?

Midnight in ART (0 0 * * *) is 0 12 * * * in JST.
