Halfway point between winter and spring

Besides Valentine’s Day and Ash Wednesday, today has another reason to be observed. Today is approximately the halfway point between winter and spring. So far, the winter has not been very severe. The temperature fell below zero only a few days in January, but daily high and low temperatures have averaged mostly above normal for approximately four weeks. The first day of spring this year is March 19th, and the changeover to daylight saving time will happen four Sundays from now on March 10th.
There is one extra day this year before the arrival of spring because February has 29 days as 2024 is a leap year.
