Summer And Winter Solstice 2024 Vakantie. The end of fall is marked by the winter solstice—the day with the fewest hours of sunlight throughout the year, therefore making it the shortest day and longest night of the year. It marks the northern hemisphere’s shortest day (first day of winter) and southern hemisphere’s longest day (first day of summer).

When do the four seasons start in 2024—for spring, summer, fall, and winter? The summer solstice signals the beginning of astronomical summer and the winter solstice signals the beginning of winter.
