Jyeshtha (month)

Jyeshtha (IAST: Jyēṣṭha) is the third month of the Hindu lunar calendar and the Indian national calendar. The name of the month is derived from the position of the Moon near the Jyeshthanakshatra (star) on the full moon day. The month corresponds to summer (Grishma) season and falls in May–June of the Gregorian calendar.

In the Hindu solar calendar, it corresponds to the month of Vṛṣabha and begins with the Sun's entry into Taurus. It corresponds to Joishtho, the second month in the Bengali calendar. In the Tamil calendar, it corresponds to the third month of Āni, falling in the Gregorian months of June–July. In the Vaishnav calendar, it corresponds to the third month of Trivikrama.

In the Hindu lunar calendar, each month has 29 or 30 days. The month begins on the next day after Amavasya (new moon) or Purnima (full moon) as per amanta and purnimanta systems respectively. A month consists of two cycles, Shukla Paksha (waxing moon) and Krishna Paksha (waning moon), each with 15 individually-named thithi (days); each thithi occurs twice per month.
