Spot Date-Line Shifts at a Glance

Late-night irst times can land on a different date in cet because of the 2 hours and 30 minutes offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.

The half-hour offset between irst (UTC +3:30) and cet (UTC +1) already makes mental math tricky — add Daylight Saving Time and the gap can shift further. This converter uses live UTC offsets, so you're always accurate.
