As we reported earlier, the largest digital distribution platform for PC games, Steam, could have the Winter sale on December 22 to January 1.
Dates aside, you can buy games at a discounted price from 11:20pm IST (9:50am PT) on December 22 to 11:40pm IST (10:10am PT) on January 1.

This has also been confirmed via posts on NeoGAF and Eurogamer.
Keep in mind that since Steam has changed the way sales function, the same games that were discounted on the Black Friday sale may not have the same price drops or may not see a reduction in price at all. At the same time, you may see some games at low prices that weren’t discounted earlier
Last year’s Steam Black Friday Sale was a landmark occasion. Reason being, Valve ensured there was one price for a game through the entire sale rather than having a discounted price followed by a flash sale or a daily deal which drove it down even further.

“In past sale events, we've asked for two discounts--a duration discount that runs for the length of the sale, and a feature discount that runs in the event that a game is featured on the front page. This year, to optimise the sale for customers and to allow us to feature and recommend your products in more ways to more customers, we're asking for just one discount, to run the length of the sale,” a post on the Steamworks Developers group read at the time.
