Phrase of the Day 42: 'once in a blue moon'

"once in a blue moon"

definition: a very rare event

(jednou za uherský rok, skoro nikdy)

example: "I see Jeff once in a blue moon; he is always working"

origin: A blue moon was originally cited as something impossible and later came to mean unlikely. There are rare examples of the moon actually appearing blue, after volcanic eruptions or unusual weather conditions. Another possible derivation is from The Maine Farmers' Almanac. When there were two full moons in a calendar month the first was printed in red, the second in blue.
