The Dota 2 ranked seasons that have taken place so far had an average duration of seven months. Season 3 is expected to end in August or September 2019.
It is impossible to predict the exact day, so the countdown below is just an approximation to the estimated month, but be aware that the season might end even a few weeks or a month later!
Valve doesn’t provide any info on the ranked season duration inside the game client, but usually they alert on the official Dota 2 Twitter a few weeks before its conclusion. I will update this page and the countdown as soon as fresh news is available.
In the table, you can find the history of the starting and ending date of each season.
|Season||Start Date||End Date|
|1||Nov 22, 2017||Jun 5, 2018|
|2||Jun 6, 2018||Jan 28, 2019|
|3||Jan 29, 2019|

Ranked seasons and Valve Time
Valve introduced the ranked seasons with the Dueling Fates update in November 2017. They announced that each season would have had a duration of six months, but so far “Valve Time” influenced their actual end date.
The first Dota 2 ranked season had a span of six and a half months, while the second one lasted for seven and a half months.
Season 4 end date
Considering all the info and data at our disposal, the third ranked season should end in August because it started on January 29th, 2019.
August is a special month for Dota 2 players because of The International, and I am pretty sure that Valve won’t release the new season prior the end of their main tournament.
Overall, we can expect the start of season 4 at the end of August or in September 2019.
If they decide to start it after the new yearly patch, we might have to wait a few months more. The previous two game-changing updates - 7.07 and 7.20 - have been published on October 31st, 2017 and November 19th, 2018 respectively.
