How the date is set

The solstices happen when the Earth's tilted axis points most directly towards or away from the Sun. In the UK the winter solstice falls on 21 or 22 December and the summer solstice on 20, 21 or 22 June. The date moves because the calendar year (365 or 366 days) doesn't match the solar year of about 365¼ days, so each solstice comes almost six hours later each year until a leap day pulls it back. That is why the 2027 winter solstice is in the early hours of 22 December, and the 2028 summer solstice is on 20 June.

Sunrise to sunset in local time (GMT in December, BST in June), calculated for each city centre with standard refraction. Published tables can differ by a minute.

The further north you are, the bigger the swing: Edinburgh has about 50 minutes less daylight than London in December and about an hour more in June.

Why the darkest evenings come before the solstice

The earliest sunset in London is around 12 December, at about 3:51pm, and the latest sunrise is around 30 December, at about 8:06am. The solstice sits between them. The gap comes from the Earth's elliptical orbit and its tilt, which make solar noon drift later through December. So evenings start getting lighter about ten days before the shortest day, while mornings keep getting darker until the new year. The clock change on 25 October 2026 had already moved sunset an hour earlier.

Stonehenge and the solstice

Stonehenge is aligned on the midwinter sunset and the midsummer sunrise. English Heritage usually opens the stones for managed access at sunrise around both solstices; check the English Heritage solstice page for the confirmed 2026 date and conditions before travelling.
