January brings a subtle yet significant increase in daylight across the United States, even as winter remains in full swing. Following the winter solstice on Dec. 21, days begin lengthening gradually, with only seconds of change at first. By the end of January, southern cities like Orlando gain about 28 minutes of daylight, while northern locations such as Seattle experience over an hour more. This increase signals the slow approach of spring, though the sun’s low angle still provides limited warmth. Longer days will continue building toward warmer weather as the sun climbs higher in the months ahead. https://www.accuweather.com/en/space-news/january-quietly-brings-a-big-change-to-daylight-across-the-us/1850342
