Questions

How do I convert a cron expression from MSK to AST?

AST is currently 7 hours behind MSK. Subtract 7 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 MSK) becomes 0 2 * * 1-5 in AST.

What is the time difference between MSK and AST?

Moscow Time is UTC+3 and Atlantic Time is UTC-4 / UTC-3. Right now aST is currently 7 hours behind MSK.

Does daylight saving time affect MSK to AST cron conversion?

AST observes daylight saving time, so the difference between MSK (UTC+3) and AST (UTC-4 / UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight MSK in AST cron?

Midnight in MSK (0 0 * * *) is 0 17 * * * in AST, on the previous day.
