Fall (autumn) ends on different dates depending on the definition used:

• Astronomical fall ends at the winter solstice, which occurs between December 20 and December 23 in the Northern Hemisphere. For 2025, this is on Sunday, December 21, 2025.
• Meteorological fall ends on November 30, as it is defined as the three months of September, October, and November.

Most of North America and Europe use the astronomical definition, while some regions like Australia and New Zealand use the meteorological system (though the seasons are opposite there).

Hence, in 2025, fall will end either on November 30 (meteorological) or December 21 (astronomical).
