Phalguna (Hindi: फागुन phaagun or फाल्गुन phaalgun) is a month of the Hindu calendar. In India's national civil calendar, Phaalgun is the twelfth month of the year, beginning on 20 February and ending on 21 March (or 20 March during leap years).

In lunar religious calendars, Phalgun may begin on either the new moon or the full moon around the same time of year, and is usually the twelfth month of the year. The holidays of Holi (15 Phalgun) and Maha Shivaratri (14 Phalgun) are observed in this month.

In solar religious calendars, Phaalgun begins with the Sun's entry into Aquarius, and is usually the eleventh month of the year.
