Yes it is for my resume. R/Sir I wouldn't dare object you but I'm a bit confuse here. Shouldn't we use a preposition "in" between project and April 2013? Or it's alright without "in"?
You would need in if you only gave the month or the year, but not if you give the specific date(s). I worked on the project in 2013. I worked on the project in April 2013. I worked on the project 4-20 April 2013.
