When Does Winter Begin? First Day & Dates
Winter is a season of cozy sweaters, holiday festivities, and, depending on where you live, snow-covered landscapes. But when exactly does winter begin? It turns out, there are two different ways to mark the start of winter: astronomically and meteorologically.
Astronomical Winter
The astronomical beginning of winter is defined by the Earth's position in its orbit around the sun. In the Northern Hemisphere, winter commences on the winter solstice, which is the day with the shortest period of daylight. This typically falls on:
- December 21st or 22nd
On the winter solstice, the Northern Hemisphere is tilted farthest away from the sun. After the winter solstice, the days gradually get longer, marking the slow return of sunlight.
Meteorological Winter
Meteorological winter is based on annual temperature cycles rather than the Earth’s position. It is defined as the three-month period that is typically the coldest in the Northern Hemisphere: — Shawn Michaels: The Heartbreak Kid's Story
- December 1st to February 28th (or 29th in leap years)
This fixed date system is used by meteorologists and climatologists for easier temperature record-keeping and comparison of seasonal and monthly statistics.
Why Two Different Dates?
The difference between the astronomical and meteorological definitions of winter exists for practical reasons. The meteorological definition provides a consistent timeframe to compare winter statistics from year to year. Meanwhile, the astronomical definition marks the true celestial event of the Earth's tilt.
