This Friday (31st July) marks the first Blue Moon to be seen over London — well, the entire planet actually — since 2012.

A full moon occurs roughly every 29.5 days, and a Blue Moon is when two full moons occur in the same month.

Sadly, the moon doesn’t honour terrestrial human calendars by putting on a show, it simply carries on as normal. No blue from the blue moon.


But, if you are out and about on Friday night and see the moon, point out how special it is to your romantic companion. There wont be another one until January 2018.

Then again, watch out for werewolves.

This website has been running now for just over a decade, and while advertising revenue contributes to funding the website, but doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether its a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

If you like what your read on here, then please support the website here.

Thank you

    Once in a blue moon = slightly more often than once every three years (and then two come along at once). A bit like Olympic Games used to be, only more common. Not as rare as transits of Venus, say!

    Such a dull definition of a blue moon. I prefer waiting for a properly blue moon. I am old enough to remember old people talking about the blue moons that followed Krakatoa blowing its top in 1883, but I was too young then to realise how interesting that was.
