Bundle up, everyone — winter begins tomorrow, Dec. 21.
The winter solstice, the traditional start to the season, falls at 3:12 a.m. PST. That ushers in the shortest day and longest night of the year, with the latest, southernmost sunrise (7:22 a.m.), the earliest, southermost sunset (4:55 p.m.) and the lowest appearance of the sun in sky at noon.
According to almanac.com, it's the earliest arrival of winter since 1896.
According to some, it's the end of the world, as forecast by the Mayan calendar.
East Bay Regional Park District rangers are leading two hikes — one pre-dawn, one in evening moonlight — for those hardy souls who want to celebrate the season with some exercise.
Meet at the trail gate of the Tilden Park Nature Area at 6:15 a.m. to climb Wildcat Peak and watch the sunrise; return by 8:15 a.m. Recommended for ages 10 and over. No advance registration required. Bring your own coffee!
