Hello everyone :)

so I've found this awesome way to add top coder & code forces contests to your Google calender also some other contests as well

codeforces : here is the link just hit the +google calender in the bottom right corner.

TopCoder : Go to this link select what you want and follow the instructions

other contests (including topcoder & code forces ) by Hacker rank . but i don't advice using it as it duplicates the events but you can give it a try.

thank you

UPD1 : if you can translate it to Russian please do and send it to me and i'll update the post
