Questions

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

AST is currently 4 hours behind WET. Subtract 4 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 WET) becomes 0 5 * * 1-5 in AST.

What is the time difference between WET and AST?

Western European Time is UTC+0 / UTC+1 and Atlantic Time is UTC-4 / UTC-3. Right now aST is currently 4 hours behind WET.

Does daylight saving time affect WET to AST cron conversion?

WET and AST observe daylight saving time, so the difference between WET (UTC+0 / UTC+1) and AST (UTC-4 / UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight WET in AST cron?

Midnight in WET (0 0 * * *) is 0 20 * * * in AST, on the previous day.
