This is the system used by meteorologists and climatologists to group the three coldest months into a consistent 90-day block. This makes it easier to track weather trends and compare seasonal statistics from year to year.

The reason for the discrepancy between the astronomical and meteorological definitions of winter lies in the Earth's slightly elliptical orbit around the Sun and the tilt of its axis. As a result, the seasons do not begin on the exact same date every year, and the meteorological definition provides a more practical and consistent way to divide the year into seasons.

Note: These dates shift slightly each year (by a day or so).
