New Year Celebration typically is marking the end of a year (a full orbit around the sun) and starting a new year. Different parts of the world mark this date using different calendars. The most popular is the Gregorian Calendar, which observed in almost all parts of the world. Additionally, in bhārata dēśa, two additional calendars are closely followed, especially for observing and celebrating our religious festivals and events. These calendars are either entirely based on movements of the sun when observed in a geocentric manner or the combined movements of the moon and the sun (in a luni-solar) calendar.

yugādi, is the new year based on luni-solar calendar, which is observed in several parts of bhārata. In layman’s terms, it is the first new moon after the spring equinox. There are several references online that help one understand how this is determined or calculated. yugādi is called guḍi pāḍva in certain regions.

Gujarati New Year (bestu varāsat) is celebrated the day after dīpāvalī. This is also based on the luni-solar calendar.

Tamil New Year’s day and viṣu are both based on the solar calendar and is marked by the day when sun enters the meṣā or Aries, which typically occurs on April 13 or April 14 (per the Gregorian Calendar).
It is typical to make resolutions concerning what one hopes to accomplish in the next year. Resolutions are nothing more than what we call sankalpa in our bhātīya languages.

A popular ritual for celebrating the new year includes serving food that symbolizes good fortune. Additionally, other rituals can be performed depending on the astrological predictions for the upcoming year.
