Questions

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

AST is currently 9 hours behind PKT. Subtract 9 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 PKT) becomes 0 0 * * 1-5 in AST.

What is the time difference between PKT and AST?

Pakistan Standard Time is UTC+5 and Atlantic Time is UTC-4 / UTC-3. Right now aST is currently 9 hours behind PKT.

Does daylight saving time affect PKT to AST cron conversion?

AST observes daylight saving time, so the difference between PKT (UTC+5) and AST (UTC-4 / UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight PKT in AST cron?

Midnight in PKT (0 0 * * *) is 0 15 * * * in AST, on the previous day.
