It takes the Earth a little more than a year to compete one orbit around the sun. The Jilian calendar's method of allowing for the extra time needed was so out of sync that it was off by several days when it was finally replaced. The Gregorian's method of adding one day every four years (February 29) was much more accurate and much easier to use. That is why it is still in use hundreds of years after it was invented and is used by most nations on the planet. It does what it is supposed to do and does it very well.
