“According to this almanac, as the Full Moon in July and the first Full Moon of summer, the Algonquin tribes of what is now the northeastern United States called this full Moon the Buck Moon.”
The Buck Moon is believed to be named after male deer or bucks sprouting new antlers around this time of the year.
Starting in early spring, bucks will grow new antlers which then cover in velvet around July and August.
Mr Johnston said: “They also called this the Thunder Moon because of early summer’s frequent thunderstorms.”
In Europe, July’s Full Moon is also known as the Rose Moon, Mead Moon or Hay Moon after the hay harvest.
