Summer Solstice
Night of Saturday, October 27 to Sunday, October 27, 2026
What is the summer solstice?
The summer solstice is a moment in the year when the sun reaches its highest point in the sky, which generally occurs around June 21 in the Northern Hemisphere and around December 21 in the Southern Hemisphere. It is the moment when daylight is at its longest in the Northern Hemisphere and nighttime is at its longest in the Southern Hemisphere. This moment marks the beginning of summer in the Northern Hemisphere and of winter in the Southern Hemisphere.
Spring forward to daylight saving time
Switching to daylight saving time means turning your clock back one hour: at 3 a.m. it becomes 2 a.m. The change takes place every year on the last Sunday of October.
Relationship between the switch to daylight saving time and the summer solstice
In many regions of the world, the switch to daylight saving time occurs at roughly the same time as the summer solstice, although the two are not directly linked astronomically. The connection between the two is that the switch to daylight saving time is often introduced to make the most of daylight during the sunniest months of the year, which often corresponds to the period around the summer solstice in the Northern Hemisphere. However, decisions regarding the switch to daylight saving time are a matter of local policy and legislation, and the exact dates can vary from country to country.
