Today is Hanuman janmotsav., that celebrates the birth of Hindu God Hanuman and seek his protection and blessings.
I celebrate him on this day by reciting devotional prayers like hanuman chalisa, ramayana slokhs.
We keep a Diya or jyoti on chowki infornt of the photo frame of lord Hanuman. It is a symbol of knowledge, purity,goodluck and prosperity.
We offer Prasad in the form of bananas, coconut and some homemade sweets. People usually goes to temples to seek his blessings.
