Dota 2 ranked Season 4 end date
The Dota 2 ranked seasons that have taken place so far had an average duration of seven months. Season 4 will end in October 2020.
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.
Update
Starting from the end of Season 4, the MMR reset is optional. The recalibration is spread out as much as possible to not create too much volatility, so that the players involved will be able to do it in a more stable environment.
Recalibration starting dates: from October 22, 2020 to November 22, 2020.
Upon logging in, you can go to Settings, and under the Account tab there is a new MMR Recalibration section.
To prevent everyone from recalibrating at once, start-times will be spaced out evenly between October 22, 2020 and November 22, 2020 and can be activated anytime until the Season is over.
Feel free to press the button the moment it’s available to you, never press it, or warm back up to competitive play before activating it.”

It is impossible to predict the exact time of the day, so the countdown below is just an approximation timed to the indicated day.
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 | Sep 19, 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.
Below, you can find the approximate duration of each season:
Season 1: 6 and a half months
Season 2: 7 and a half months
Season 3: 8 months
Season 4 end date
I don’t think season 4 will be longer than season 3: many players complained about its duration as they expected it to end a month before (just after TI9).
It looks like seven months is the average duration nowadays, so season 4 might end in May or June 2020. Instead, if Valve decides to follow the initial six-month rule, it will end at the start of spring, in March.
Updates history
Wykrhm Reddy announced that the Battle Pass will be released early next week (the last week of May).
Usually, Dota 2 updates take place on Tuesday and Thursday, so I believe the BP will land on May 26th. We don’t know yet if it will also start the new Dota 2 season, but this is the most reliable prediction.
The official Dota 2 Twitter declared that we will have the new Battle Pass tomorrow, May 25th.
The Battle Pass didn’t start the new Dota 2 season. Now, predicting the season end date is extremely difficult because Valve is not adhering to the initial 6-month duration, and we have no clues left.
Season 4 launched in September 2019, and the BP will conclude on September 19th 2020, so I think the current season could last for an entire year.
The Battle Pass will be extended for 3 more weeks, until October 9th.
We haven’t started a new season yet because we’ve been trying to decide whether the resets, at least in the form we’ve been doing, are productive or not. If you have any thoughts on this topic we would be interested in hearing it.”

Next week we’re releasing some new updates to Dota Plus. Among them will be updates to Guilds, a new Dota Plus Season, and a new MMR reset mechanism.”

Season 3 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.
