Ada Lovelace Day
Ada Lovelace Day is an international celebration of the achievements of women in science, technology, engineering and maths (STEM).
New ALD shop
You can now buy Ada Lovelace posters, prints, greetings cards, and notebooks from our RedBubble shop! All profits go to supporting Ada Lovelace Day, and we’ll be adding to our range there over coming months.
Sponsorship prospectus now available
Our sponsorship packages for 2015 are now available, so please take a look. We have packages for companies of all sizes, covering our event, our website and special projects. We are also able to tailor packages to sponsors’ specific needs. If you’re interested in supporting women in STEM, please get in touch!
Ada Lovelace Day Live! 2015
This year, our our annual flagship event is being hosted by the Conway Hall Ethical Society at Conway Hall, Holborn, on the evening of 13 October. Details to come!
Last year, Ada Lovelace Day Live was held at the Royal Institution. The evening featured talks and performances by mathematician Dr Hannah Fry, musician Caro C, structural engineer Roma Agrawal, geneticist Dr Turi King, TV presenter Konnie Huq, artist Naomi Kashiwagi, technologists Steph Troeth, physicist Dr Helen Czerski and was hosted by our inimitable ALD Live producer, Helen Arney! You can see videos from the evening on the Ri’s YouTube channel, and photographs on Flickr.
The support of the Ri also allowed us to put together an afternoon event for 11 – 16 year olds, exploring the role and work of women in STEM. Speakers included sustainability innovator Rachel Armstrong, neuroscientist Sophie Scott, mathematician Hannah Fry, roboticist and theremin player Sarah Angliss, engineer Roma Agrawal, and dwarf mammoth expert Victoria Herridge, and was hosted by our very own Helen Arney!

Inspiring women in STEM
Every year we encourage you to take part, no matter where you are, by writing something about a woman, or women, in STEM whose achievements you admire. You can browse our list of posts from 2014 to see who has inspired other people!

A Passion for Science
From the identification of the Horsehead Nebula to the creation of the computer program, from the development of in vitro fertilisation to the detection of pulsars, A Passion for Science: Stories of Discovery and Invention brings together inspiring stories of how we achieved some of the most important breakthroughs in science and technology. Read our sample chapters.
From Kiribati to Howland Island
In the middle of the Pacific Ocean, on Kiritimati Island, Ada Lovelace Day begins. Also known as Christmas Island, the coral atoll is situated in the Line Islands and is a part of the Republic of Kiribati. It lies 14 hours ahead of GMT/UTC, and 13 hours ahead of British Summer Time.
It continues for a mindbending 50 hours, until midnight on Baker Island and Howland Island, two uninhabited atolls which are actually further west than Kiritimati Island but which sit on the other side of the International Date Line. Both islands are 12 hours behind GMT/UTC, or 13 hours behind BST.
With 50 hours to play with, you will have plenty of time to get something written, published and into our collection! (Hint: You can actually add your story at any time, we’re not that strict!)

Ada Lovelace Day in a nutshell
Ada Lovelace Day is about sharing stories of women — whether engineers, scientists, technologists or mathematicians — who have inspired you to become who you are today. The aim is to create new role models for girls and women in these male-dominated fields by raising the profile of other women in STEM.
Why October 13?
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.
So, we use the second Tuesday in October, which is 13 October 2015.
Why not just used 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 just 36, it would feel inappropriate to celebrate her deathday on 27 November.
