wtf is bulgarian-holidays.el?

This is a small Emacs extension that adds Bulgarian holidays to your calendar application. If you use Emacs, a powerful text editor popular with programmers and power users, this package makes it so that when you open the built-in calendar, it automatically highlights and displays important Bulgarian holidays and observances alongside the standard dates. The way it works is straightforward: the package contains a list of Bulgarian holidays (both fixed dates like New Year's Day and moveable ones like Easter) and integrates them into Emacs's calendar system. Once installed, whenever you view a calendar month in Emacs, those holidays appear marked or highlighted, so you can see at a glance when they fall. It's similar to how your phone's calendar app might show national holidays for your country. You'd use this if you're Bulgarian, live in Bulgaria, or work with Bulgarian colleagues and want your Emacs calendar to reflect the local holiday schedule. It's particularly useful if you're already an Emacs user who relies on the calendar for scheduling and planning, why look up Bulgarian holidays elsewhere when they can be built right into your editor? The README provided is minimal and doesn't go into detail about installation steps or which specific holidays are included, but the core idea is simple: it's a small, focused tool that solves one problem well for a specific audience. It's the kind of extension that matters most to people who spend a lot of time in Emacs and want their tools customized to their local context.
