How fast do the days get longer after December 22 how many minutes do we gain each day?

After December 22, the days begin to lengthen as we move towards the spring equinox. On average, we gain about 1 to 2 minutes of daylight each day in the weeks following the winter solstice, with the amount increasing as we approach spring. By late January, the gain can reach around 2 to 3 minutes per day, and by March, it can be even more pronounced. This gradual increase continues until the longest day of the year in June.
