Sri Ramalakshmana Dwadashi is an extremely auspicious vrat or observance which is celebrated on the dwadashi day. The Ramalakshmana Dwadashi falls on the month of Jyestha, on the Dwadashi of Shukla paksha, the day after the very effective Nirjala Ekadashi; according to traditional Hindu calendar. According to Gregorian calendar, this vrat is observed in the month of June, on the waxing phase or the bright phase of the moon. Sri Ramalakshmana Dwadashi is also observed as Champaka Dwadashi. It is believed that King Dasharath observed this vrat to get Lord Rama as his son by the next year's Chaitra Maasa Navami.
