| Winter is one of the four seasons of temperate zones. Astronomically,
it begins with the winter solstice (around 21 December in the Northern hemisphere
(except in the Irish Calendar where it is counted as the full months of
November, December and January), and 21 June in the Southern hemisphere),
and ends with the spring equinox (around 21 March in the Northern hemisphere
and 21 September in the Southern hemisphere). However, sometimes it is counted
instead as the whole months of June, July and August in the Southern hemisphere
and December, January and February in the Northern hemisphere.
Wintering is a term used to refer to seasonal climate-related migrations, such as those of migratory birds or Monarch butterflies. By extension, it is also refers to seasonal agricultural practices, such as transferring beehives to warmer locations. |
