Julian date is sometimes used to synchronize timing for encrypted radio systems. My understanding is that early radio systems adapted it because it was used by astronomers. Astronomers used it because it didn't skip any days which would cause issues tracking long term astronomical cycles.

And still use, in fact!
I deal with those radio systems occasionally and I've always wanted to find or modify a digital watch to display the Julian date. It feels like that would be such a simple firmware change to something like a g-shock.
