June 23, 2015 is Midsummer's Night Eve, or St. John's Eve. St. John is the patron saint of beekeepers.
June is also the leading month for U.S. weddings and the month when hives are full of honey. The full moon is called the Mead Moon because fermented honey is made into mead. It's also the basis of the expression "honeymoon."
There's a Swedish proverb that says "Midsummer Night is not long but it sets many cradles rocking."
