This is CompoHub, a little site that lists all kinds of game development events that are available all around the world.
Just drag the timeline above to see to the future. Or to the past if your memory is weak.
All the times are in the time zone of your choice.
If you think this site is missing an event or an important feature or you find a bug, use the issue tracker and I'll look into it.
For anything else, you can comment on the dev log.
You might want to follow updates easily, so create a personal feed for yourself.
Also, I created a page for some interesting stuff you might want to see.
For conferences and other physical events related to games, check out Gameconfs.
