So... what exactly is a g4g event? Great question!
We believe there's more than one way to get girls excited about STEM, and so we've built a whole lineup of ways to do it! Here's what you'll find on our calendar.
Whether you find us in your classroom, at your school, in a museum, or at your company, these g4g days bring anywhere from 30 to 300 girls together from local schools and diverse backgrounds.
You'll find these events popping up in cities all over the world, from our home base in Brussels to communities across the US, Europe, Latin America, the Middle East, Africa, and Asia! All thanks to incredible partners and team of volunteers!
Wherever we land, girls can count on one thing: a day full of curiosity, inspiring women in STEM, hands-on discovery, and proof that anything is possible!
Take a look at where we are going:
We're always cooking up something new! Whether we're heading back to a city we love or launching in a brand-new one for the very first time, every event on this list means more girls are about to fall in love with STEM. Take a look at what's coming up in Fall 2026:

Take a look at where we’ve been:
That's what's coming up, but we've also been busy! From one email to hundreds of events across five continents, greenlight for girls has been showing up in cities all over the world for years now. Take a scroll through and see for yourself: maybe we've already been to your city, maybe you caught us at an event, or maybe a friend, a teacher, or your school brought you along for the ride. Wherever it was, chances are we turned an office, a lab, or a classroom into a playground for robotics, coding, chemistry, and everything in between. So go ahead and see if you spot yourself in the memories below!
