A free mod for Stardew Valley, by Alpha_Omegasis.

This is useful to know the upcoming events that you need to plan for in the game. It also allows you to easily access the daily quest board. The list is sorted by date and time and it displays the current month and year for each event.
To install this mod you need to download the latest version of SMAPI from the official website. You will also need to unzip it into Stardew Valley/Mods.
