List of Hindu festivals

Explanatory note
Hindu festival dates

The Hindu calendar is lunisolar but most festival dates are specified using the lunar portion of the calendar. A lunar day is uniquely identified by three calendar elements: māsa (lunar month), pakṣa (lunar fortnight) and tithi (lunar day).

Furthermore, when specifying the masa, one of two traditions are applicable, viz. amānta / pūrṇimānta. If a festival falls in the waning phase of the moon, these two traditions identify the same lunar day as falling in two different (but successive) masa.

A lunar year is shorter than a solar year by about eleven days. As a result, most Hindu festivals occur on different days in successive years on the Gregorian calendar.

Hindus celebrate a significant number of festivals and celebrations, many of which commemorate events from ancient India and often align with seasonal changes. These festivities take place either on a fixed annual date on the solar calendar or on a specific day of the lunisolar calendar. The observance of these festivals often varies by region, with many celebrated predominantly by particular sects or in specific areas of the Indian subcontinent.
