There is a lot of holidays, which are dedicated to IT. For example: Tester Day (September 9th), Programmer’s Day (256th day of the year), BlogDay (August 31st), Sysadmin day (last friday of July) and some others.

We decide to start celebrating a #TwitterDay - 140th day of the year, relating to 140 symbols restriction in Twitter. So, it will be the May 20th in every single year, or May 19th in every leap year.

Here you can share the information about Twitter Day with your friends and followers. Or just tweet about it in your twitter with #twitterday hashtag.
