Dates for the Steam Summer Sale 2019 have been leaked. This seems to be a rather common thing with these sales for the past few years now. I think every major Steam sale has had its date leaked weeks ahead of time and this one is no exception.

According to the leak, the Steam Summer Sale 2019 begins on June 25 and will conclude on July 9.
