A free mod for Stardew Valley, by atravita.
The Holiday Sales mod for Pelican Town: Town Manager will keep your favorite stores and shops open during Festivals. The idea is that if you’re going to visit the town, you might as well take advantage of it as the shops’ doors are never close.
You won’t have to worry about finding a place to shop, as the Holiday Sales mod will keep all the shops open during Festivals.
You can play in single player, multiplayer, and split-screen mode. This mod is compatible with most of the mods available.
