1 January opens the year in the Gregorian calendar, now the civil calendar of most countries, and is among the most celebrated public holidays in the world, often greeted with fireworks at midnight as the year begins in each time zone. January is named for Janus, the Roman god of gateways and beginnings, and the Kalends of January became Rome's new year after it became the day new consuls took office in 153 BCE. New Year's resolutions are a common custom.
