The last time a blue moon coincided with New Year's Eve was in 1990.
The next opportunity will come in 2028.
Is this a celestial sign of a better decade to come?
It will not be literally blue; the term "blue moon" actually refers to when there are two full moons in a given calendar month, an astronomical rarity that occurs just seven times every 19 years, hence the famous phrase "once in a blue moon."

I shall be singing this with my arms around my partner Colin tomorrow night- looking up at the moon ( Two minutes into the video you get the Spanish words as seen below with the English translation)
A luna esta en el cielo
con todas las estrellas
brillando muy illuminante
The moon is in the heavens
with all of the stars
shining so brightly
