I think you’re talking about this, which the article says used to called Julian date

BackOnMyBS@lemmy.world 1 year agoI don’t remember specifically where I got the idea, but when I was in the military, we used it for operations and never used the month. We would solely state the day of the year. If that has another name, then that’s what I’m talking about. A yearly calendar where the date is the day of the year in sequential order without months.

The Julian calendar is the one that has no special rule for leap years. It is currently October the 12th in the Julian calendar.
The calendar that is used all around the world is the Gregorian calendar.
What you mean is called the ordinal date (at least by Wikipedia: en.wikipedia.org/wiki/Julian_calendar, see the disambiguation note at the top)
