Ada Lovelace Day (ALD) is an international celebration day 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 features a flagship Ada Lovelace Day Live! ‘science cabaret’ event in London, UK, at which women in STEM give short talks about their work or about other women who have inspired them, or perform short comedy or musical interludes with a STEM focus. In 2015, ALD was held on 13 October and we packed out Conway Hall, our host venue for Ada Lovelace Day Live!, with a diverse and appreciative audience.
The day also includes dozens of grassroots events around the world, organised entirely independently from the ALD Live! event. These events take many forms — from conferences to Wikipedia ‘edit-a-thons’ to pub quizzes — and appeal to all ages, from girls to university students to women with well-established careers. Last year and was the biggest ALD to date with over 150 independently organised Ada Lovelace Day events, in 82 cities, in 25 countries.
Sponsorship packages for 2016 are now available, with options for companies of all sizes to support our annual event, podcast, resources database and special projects such as our education pack. We can also tailor packages to suit sponsors’ specific needs. If you’re interested in supporting women in STEM, please get in touch!
Organise your own ALD event
Every year, people around the world, people like you, organise their own events for Ada Lovelace Day. We've put together a handy organisers’ pack for inspiration, advice and resources to help people get involved by organising their own events. You can also chat to other organisers about what they are doing on our community forum!
Ada Lovelace Day Live! 2015
Last year, our annual flagship event was hosted by the Conway Hall Ethical Society at Conway Hall, Holborn, on the evening of 13 October. Playing host to the UK’s most fabulous women in STEM, ALD Live is an entertaining evening of geekery, comedy and music suitable for women and men, and girls and boys over the age of 12.
Speakers included Mars Rover engineer Abigail Hutty, astrophysicist and science communicator Dr Jen Gupta, nanochemist Dr Suze Kundu, musician and mathematician Professor Elaine Chew, neuroscientist Professor Uta Frith, science television producer and director Lucy Haken, and our very own Suw Charman-Anderson. Our compère was the inimitable Helen Arney.
We were also delighted to offer free tickets to school and youth groups (12+ years old), as well as families and individuals, for whom the cost of the event would otherwise be prohibitive. We are grateful to Slack, the messaging app for teams, for their support in making this happen.
Posters, notebooks, greetings cards
You can now buy Ada Lovelace posters, prints, greetings cards, and notebooks from our RedBubble shop! We have a full range of merchandise featuring Ada Lovelace and palaeontologist Mary Anning, plus our two careers posters available for sale.
All profits go to supporting Ada Lovelace Day, and we'll be adding to our range over coming months.
Our Passion for Science
Our mission at Ada Lovelace Day is to raise the profile of women in STEM, and we think our two anthologies about the inventors, pioneers, technologists, scientists, engineers and mathematicians, both modern and historic, do exactly that! Indeed, only one thing unites these stories, whether it is the ground-breaking use of scuba diving to study sharks, or the rigorous physical and psychological testing of Mercury astronaut hopefuls — all our protagonists are women.
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, 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.
Journalist and TV presenter Maggie Philbin said that the book is "a brilliant read" and a "powerful, important and engaging record of women’s experiences in science and technology. Some stories I thought I knew, others were completely fresh to me, but every one captured the spirit of a woman I would have loved to have been."
Our second book, More Passion for Science: Journeys Into the Unknown, explores topics as diverse as the Air Transport Auxiliary ferrying planes around the UK during the Second World War under incredibly dangerous conditions, the programming of the first electronic general purpose computer, and the building of the Brooklyn Bridge.
“This is a wonderful collection of stories written with charm and eloquence by a wonderful collection of people," said mathematician and broadcaster Dr Hannah Fry. "There are captivating tales of celebrated characters and intriguing hidden stories from those sidelined from the spotlight."
Share your stories about 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 don’t have to write a blog post, you can post anywhere, as long as it is public.
- Anyone can get involved, not just women
- Celebrate in whichever language you like
- Add your story to our list
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.
Who was Ada Lovelace?
Born in 1815, Ada Lovelace collaborated with inventor Charles Babbage on his general purpose computing machine, the Analytical Engine. In 1843, Lovelace published what we would now call a computer program to generate Bernoulli Numbers. Whilst Babbage had written fragments of programs before, Lovelace's was the most complete, most elaborate and the first published.
More importantly, Lovelace was the first person to foresee the creative potential of the Engine. She explained how it could do so much more than merely calculate numbers, and could potentially create music and art, given the right programming and inputs. Her vision of computing's possibilities was unmatched by any of her peers and went unrecognised for a century. Read our biography of Lovelace to find out more!
Why October 11?
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 11 October 2016.
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.
