Hi there!
As always, this year “Software Freedom Day” is going to be celebrated on the 3rd saturday of September - for 2023 that is the 16th of September.
This year marks a special SFD: it’s its 20th edition!
Take some time, look at the events map, and consider attending to the one in your country/region. There’s nothing planned for nearby? Why don’t you organize some way to celebrate the day?
