When is ALD?

Ada Lovelace Day is held every year on the second Tuesday of October.

People often ask why Ada Lovelace Day is the day that it is. The explanation is rather mundane: the date is arbitrary, chosen in an attempt to make the day maximally convenient for the most number of people. We have tried to avoid major public holidays, school holidays, exam season, and times of the year when people might be hibernating.

Why not just use Ada’s birthday? Well, Ada was born on 10 December and, in the UK where Ada Lovelace Day is based, December is swamped by Christmas parties, making venue hire tricky and putting us in competition with traditionally unmissable employee booze-ups. Given her tragically early death at the age of 36, it would feel inappropriate to celebrate her deathday on 27 November.

If you’re not sure which are the second Tuesdays of October do not worry. To help you plan ahead, here are Ada Lovelace Day’s dates for the next hundred years:
