When Is Winter 2025 In Usa. Us school holidays and national holidays for 2024/2025. The spring 2025 intake application deadline is between july and december 2024.

It is conventional, however, to count december, january, and february as the three winter months in the us. The winter season technically begins on either 21 december or 22 december in the us since this is the date of the winter solstice for all areas above the equator.
