Riot Games announced 11 rewards that are quite appealing to League of Legends players but the fans were not sure if they commit for straight 10 days of logging in to get them. Thankfully, Riot clarified that they have an entire month to grab them.
League of Legends' 10 year anniversary included a veritable treasure trove of the new game and port announcements but also ways to celebrate the first decade of the most effective salt factory planet Earth has ever seen.
One of those ways is starting on 17 October 2019. It will give players a single mission each day, with the objective of playing one game in order to claim a reward for that day. Initially, fans thought the 10 gifts for 10 missions would have to be acquired in the 10 consecutive days leading up to League of Legends' exact anniversary, on 27 October 2019.
As it turns out, this is not the case and players will not have to do it for 10 days straight. According to a Riot Games support reply sent to one concerned player, the anniversary gifts can be acquired all the way up until 19 November 2019 at 11:00 AM PDT / 8:00 PM CEST / 3:00 AM KST (likely 20 November for KST).
Keep in mind that the daily reward missions will work the same way as the first win of the day reward. You cannot acquire the next one for a whole day after grabbing a gift. Considering the system heavily borrows from the first win of the day, it's possible the timer works the same way and is shorter than the actual 24 hours.
All things considered, there is plenty of time to grab the 11 presents Riot Games prepared for us, with the final one being the Annie skin with that Teemo/Tibbers hybrid abomination. Do we call it Teebers? Timmo?
