Daylight Saving Time starts on Sunday, and we gain 1 extra hour of light

The day after tomorrow marks the beginning of what for many internationals is the best time of the year, with up to 17 hours of light—more than twice as much as the period we are leaving behind

It’s time to change Daylight Saving Time. This weekend, we will all switch the clocks an hour later, gaining one more hour of light—something that is desperately desired by many internationals coming to Denmark from southern countries. It is well known how the lack of sunlight may affect the well-being of many people. Even though Daylight Saving Time won’t rid us of the clouds (for that, we’ll have to wait for the warmer season to approach, even though the last few days have been blessed with the sun), many will benefit from a later sunset.

In the night between tomorrow and the day after tomorrow, Daylight Saving Time will start. More precisely, on Sunday, 30 March, the clocks will be turned forward by 1 hour at 02:00 AM, meaning sunrise and sunset will occur about 1 hour later than the previous day, resulting in more evening light and less morning light. In other words, you will sleep an hour less, the sun will rise an hour later, and the sunset will be an hour later.

On Sunday, the sunrise will be at 6:45 in the morning (while it’s currently at 5:55), and dusk will be at 19:43. In about a month from now, the sunrise will be at 5:33 and the sunset at 20:42, giving us a total of 15 hours of light during the day. Around the 25th of May, it will be 4:42, 21:32, and almost 17 hours of light. As always, the lightest day of the year will be on June 21st: sunrise at 4:25, sunset at 21:57, and 17 hours and 32 minutes of daylight.

How long will we enjoy these longer days? Until Sunday, 26 October 2025, when Daylight Saving Time ends, and the clocks will be turned back by 1 hour at 03:00 AM. Sunrise and sunset will occur about 1 hour earlier than the previous day, resulting in more morning light and less evening light.

At that point, it will be a long way to darker days, culminating on the 21st of December, when the sun will rise at 8:37, set at 15:39, and the daylight will last for no more than 7 hours, 1 minute, and 15 seconds.

Still, that is a problem for the future. Ahead of us, we have spring, summer, and long days. They will start tomorrow, so save the date and check your clock!
