When converting from AST to CET, the key reference points to remember are: 9:00 AM AST equals 2:00 PM CET, 12:00 PM noon AST equals 5:00 PM CET, and 5:00 PM AST equals 10:00 PM CET. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across AST and CET
For professionals scheduling meetings between AST and CET, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 5 hours difference, the window of overlap may be limited. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
AST observes Daylight Saving Time, switching to ADT (UTC-3) during summer months. CET observes DST, switching to CEST (UTC+2). During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
