Gayatri Jayanti is observed as the birth anniversary of Goddess Gayatri, the Goddess of Veda. Being the Goddess of all Veda, Goddess Gayatri is also known as Veda Mata.
It is believed that Goddess Gayatri is manifestation of all phenomenal attributes of Brahman. She is also worshipped as the Goddess of Hindu Trimurti. She is considered as the mother of all Gods and embodiment of Goddess Saraswati, Goddess Parvati and Goddess Lakshmi.
Most people, especially in South India, observe Gayatri Jayanti during Shravana Purnima. According to Matantara i.e. due to the difference of opinions to observe Gayatri Jayanti, it is also observed on Shukla Paksha Ekadashi during Jyeshtha lunar month. Matantara Gayatri Jayanti is usually observed on the next day of Ganga Dussehra.
Devotees observe Gayatri Jayanti by making special prayers to Gayatri Mata and by repeatedly chanting Gayatri Mantra.
In modern India, Gayatri Jayanti day during Shravana Purnima is observed as Sanskrit Diwas, a day to mark the importance of Sanskrit language. Various activities, seminars and workshops are organized on the day of Sanskrit Diwas to promote the Vedic language. In current time, the usage of Sanskrit has been limited to only Puja-Patha and academic activities.
