December 2025 Sky: Geminids & Cold Moon!

December 2025 heralds the close of the year with a stunning array of astronomical events and holiday celebrations. Astronomy enthusiasts can anticipate the Geminids, widely regarded as the year's most impressive meteor shower, with its peak viewing period set from December 13th to 14th. Earlier in the month, on December 4th, the Cold Moon will grace the night sky, presenting a significant lunar spectacle.

The month also marks the winter solstice on December 21st, signifying the shortest day of the year. Alongside these cosmic events, December 2025 is filled with traditional holidays, including Hanukkah and Christmas. Christmas Day itself is a federal holiday, observed on Thursday, December 25th, leading to closures in banks, government offices, and the U.S. stock market.

Further celestial events include the Ursids meteor shower, peaking from December 21st to 22nd, and the start of the Quadrantids meteor shower on December 28th, which will continue into early 2026. These events collectively make December 2025 a month rich in both astronomical phenomena and festive observances.
