Assu
Assū (Shahmukhi: اسو; Gurmukhi: ਅੱਸੂ, Punjabi pronunciation: [əsːuː]), also spelt as Asu, is the seventh month of the Punjabi calendar, as well as the Nanakshahi calendar, which governs the Sikh tradition. The Nanakshahi solar month of Asu I begins on September 5th, after Bhadon, and ends on October 5th, being followed by Katik I. The traditional Punjabi Bikrami lunisolar month begins on the day after the Bhadon full moon and ends on the Assu full moon.
This month coincides with Ashvin in the Hindu calendar and the Indian national calendar, and September and October in the Gregorian and Julian calendars and is 30 days long.
