Aashaadha (Hindi: आसाढ़ Āsāṛh or आषाढ Āṣāḍh) is a month of the Hindu calendar. In India's national civil calendar, Āsāṛh is the fourth month of the year, beginning on 22 June and ending on 22 July. The month is known as Ādi in Tamil. In solar religious calendars, Āsāṛh begins with the Sun's entry into Cancer.
In lunar religious calendars, Āsāṛh begins on a new moon and is usually the fourth month of the year.
In the Vaishnava calendar, Vamana governs this month.
Guru Purnima, a festival dedicated to the Guru, is celebrated on the Purnima (Full Moon) day of the month. Prior to it Shayani Ekadashi, is observed on the eleventh lunar day (Ekadashi) of the bright fortnight (Shukla paksha).
