Dota itself also has this feature in your profile, teammates

thanks so much, Kowareta! and Greatlubu, that feature is great but I can't figure out how to filter by time in the Dota client

Yeah not really a way to check the time specifically. Unless you only play 2 stack with one friend you could filter your 2 stack games by time period

If you get Dotaplus on dotabuff you can check winrate with players, over a time period, or with specific heroes.
its truly worth it and possibly one of the main reasons why i have dotabuff plus! highely recomend.

yes, paying for stuff that opendota gives u free already
very smart
