Questions

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

KST 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 KST.

What is the time difference between ART and KST?

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

Does daylight saving time affect ART to KST cron conversion?

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

What is midnight ART in KST cron?

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