In Luni-Solar religious calendars, Phalgun may begin on either the new moon or the full moon around the same time of year, and is usually the eleventh or twelfth month of the year. However, in Gujarat, Kartika is the first month of the year, and so Phalguna follows as the fifth month for Gujaratis.The holidays of Holi (15 Phalguna) and Maha Shivaratri (14 Phalguna) are observed in this month.
In solar religious calendars, Phalguna begins with the Sun's entry into Aquarius, and is usually the eleventh month of the year.
Most parts of North India see early celebration of the famous Hindu festival Holi in this month. Holi is celebrated at the end of the winter season on the last full moon day of the lunar month Phalguna (Phalguna Purnima), which usually falls in the later part of February or March.
The Hindu festival of Shigmo is also celebrated in Goa and Konkan in the month of Phalguna. Celebrations can stretch over a month and may last even after the Hindu Luni-Solar New Year begins. Another popular fair is Phalguna Mela in Khatushyamji in Rasjasthan.
