Solar New Year

The Solar New Year is the beginning of the solar calendar year. This event is observed at different times of year and with varying practices in cultures across the globe. The most common bases chosen to begin a new calendar year are the winter solstice, summer solstice, the spring equinox and the autumnal equinox. South and South-east Asian solar calendars are more formally linked to astronomical events.

Some of the more widely known solar new year celebrations include:

• Enkutatash (Ethiopian calendar): about ten days before the autumnal equinox
• January 1 in the Gregorian and Julian calendars (same number, different days): at present^[a] about twelve and twenty-five days respectively after the northern winter solstice.
• Iranian New Year (Nowruz) : precisely the northern spring equinox
