Ada Lovelace Day (ALD) is an international celebration of the achievements of women in science, technology, engineering and maths (STEM). It aims to increase the profile of women in STEM and, in doing so, create new role models who will encourage more girls into STEM careers and support women already working in STEM.

Founded in 2009 by Suw Charman-Anderson, it is now held every year on the second Tuesday of October. It usually features the flagship Ada Lovelace Day Live! ‘science cabaret’ in London, UK, at which women in STEM give short talks about their work or research in an informal, theatre-like setting.

This year, Ada Lovelace Day is going back to its roots with a day of blogging, Twittering and Facebooking, just like we did in 2009. #ALD20 will celebrate women, advocates and educators in STEM. We’ll be profiling women working in STEM around the world and those women who work so hard campaigning for gender equality in industry, academia and the community.

We want you to join in by highlighting our hidden advocates, the teachers, lecturers and professors, the researchers and technicians, the women you work with, who go above and beyond to encourage and support girls and women in STEM. Who are the unsung heroines whose work is changing the future face of STEM?

You can write a blog post, record a podcast, or take part on Twitter, Facebook, LinkedIn or any other social media platform – the choice is yours. And just like back in 2009, we’ll create a database so that you can give us your links for posterity.

We've a lot more to announce coming up, so follow us on Twitter or Facebook, or subscribe to our newsletter to be kept up to date.
