I was first informed of such an event 2 years ago. I was told that it was an annual event held in September. Last year, I remembered about it 2 weeks after it was held. But this year, somehow it appeared in my mind early. I reminded myself to check out the date of the event when it was nearing september. I did not however, but i came across an article on this event in the newspaper a few days ago. And thats how i got to know the date for this year.
It is held today. Going down to check it out later. Maybe in the early afternoon. Here’s the link for more information -> http://softwarefreedomday.sg/
