A red letter day is like a unicorn sighting – rare, magical, and totally unforgettable! It's the kind of day that makes you want to throw a party, dance in the streets, or wear your fanciest hat to the grocery store. Maybe you got a promotion at work, finally turned that languishing WIP into an FO, or just had the best hair day of your life. Whatever the reason, a red letter day is a cause for celebration! It's a day when the sun shines a little brighter, the birds sing a little sweeter, and the universe gives you a big high five for being awesome.
