dBirthday, is a plugin that will allow you to easily manage birthdays, in order to make your server more welcoming.
The plugin is very easy to use, you just have to drag it into the plugins folder of your server, and restart your server.
The plugin is available and tested from 1.18.2 to 1.20.6.
There will be new features that will arrive soon, such as being able to offer a gift to a player (in advance) for his birthday or directly plan gifts for players.
