ENJOY the night sky this evening because the moon only looks like this ‘once on a blue moon’.

Or every 2.7 years, to be precise.

Two full moons in one month
Two full moons in one month

The deceptive name ‘blue moon’ refers to the second full moon occurring within a single month, which occurs roughly every 2.7 years.

There are two measures of blue moons, one by full moons in a season, and the other by calendar month.

This moon will be the last calendar blue moon until January 2018.
