Frequently Asked Questions
Why do DST dates differ between US and Europe?
Different countries chose different start/end rules based on their climate, culture, and energy needs. The US uses the second/first Sunday rule, while Europe uses the last Sunday rule. See our conversion tables for complete time zone reference.
Will DST end in Europe?
The EU voted to end mandatory DST changes, but implementation has been delayed. Each country would choose whether to stay on standard or daylight time permanently.
How do I adjust to DST changes?
Gradually shift your sleep schedule by 15-20 minutes per day leading up to the change. Exposure to bright light in the morning can help reset your circadian rhythm.
