Midsummer Eve

If you haven't celebrated Midsummer's Eve yet, tonight is your last chance. Apparently the holiday is fairly fluid on setting dates. Strictly celestially speaking, this year's summer solstice occurred June 21st at 12:45 AM EST. That means Midsummer Eve's earliest date this year was sundown on June 20th. That is the one that is most widely recognized, However, there are other ways to calculate Midsummer Night. Sometimes the birthday of St John the Baptist is used; that would make it June 23rd. Another way to calculate it is by the Full Moon nearest the summer solstice, and that is tonight.
