In meteorological terms, Winter in the northern hemisphere covers the months of December, January and February.

But, astronomically, Winter starts at the Winter Solstice, when the Sun reaches its furthest point south of 23º26.1’ - this year at 0419 UTC (~GMT) on 22 December. It will be followed by Spring, starting at the Vernal Equinox, when the Sun re-crosses the equator, at 0350 UTC on 20 March 2020.

And European clocks should re-adopt Summertime at 0100 UTC on 29 March 2020, in compliance with an EU directive since 2002, which states that ‘Summer Time’ will be observed between the last Sundays in March and October, clocks to change at 0100 UTC.
