Pokémon Go’s “Winter Holiday” event is back for 2023 and is broken up between two parts, as usual. The first part of the event runs from Dec. 18-25 and the second part runs from Dec. 25-31.
This event comes with bonus XP and Stardust from opening gifts throughout both parts. There’s also a perk of either doubled catch XP or doubled catch Stardust, depending on what you pick in a Timed Research set.
Below we list out all the Timed Research, alongside other perks from the Pokémon Go “Winter Holiday” 2023 event below.

This research lasts until the event ends on Dec. 31.
Rewards: 500 Stardust, 500 XP
After this step, you’ll be prompted with a choice: catch Pokémon or collect Stardust. Whatever you pick has importance beyond the task set you’ll get next. If you choose to catch Pokémon, you’ll get doubled catch XP, while if you opt to go after Stardust, you’ll get doubled catch Stardust. Pick whichever you need!
Rewards: Galarian Mr. Mime encounter, 1 Lucky Egg or Star Piece
If you picked XP, you get a Lucky Egg as a reward. If you picked Stardust, you get a Star Piece.

This is a paid research, so you’ll need to buy a ticket from the shop for $4.99. You can figure out if you think it’s worth buying from the rewards below. (If you like special poses and costumed Pokémon, it’ll probably be worth it for you.) Niantic’s event page notes that you’ll also get doubled candy from catching Pokémon if you buy this ticket as well. Note that it is still timed, meaning it does expire at the end of the event.
