As this day was the birthday of the Ring-bearer Frodo Baggins it became significant to the New Reckoning after the War of the Ring; corresponding to 30 Yavannië, it was made a festival in honor of Frodo. See also: Cormare
Despite this, how the Shire Reckoning, and consequently the date of Bilbo's and Frodo's birthday, corresponds with our calendar is a matter of debate. Appendix D says that our New Year's Day (1 January) corresponds "more or less" to the Shire's "9 January", and in standard years our 14 September corresponds to the Shire's "22 September" (256 days later). However, Appendix D also says that the Shire calendar's "Midyear's Day" is "intended to correspond as nearly as possible to the summer solstice." In the Shire calendar, 22 Halimath is 83 days after Midyear's Day. If we take the summer solstice to be our June 21, then Bilbo's and Frodo's birthday must be 83 days later, which is our September 12.
