There are six different types of Tithi in Hindu astrology. Jaya
Tithi is one among them. Tritiya, Ashtami are Trayodasi tithis. They are
considered generally bad tithis.
The tithis are avoided in some regions as they are
considered inauspicious.
Jaya Tithi is chosen for propitiating various forms of
Mother Goddess.
Food donation and helping people during the period will help
