The balance between permanent Last Day on Earth content and season updates has been an issue in ldoe for a while. Season updates are usually fun and exciting, but when they end you're left wanting more events and new rewarding tasks. The calendar helps ease that seasonal downtime by providing a steady stream of in-game events.
My hope is that these recycled calendar events can be combined with simple seasons to provide more development time for permanent content. This calendar update is one of the biggest quality of life updates Last Day on Earth has gotten in a long time. Big thanks to the devs for listening. :)
