    Our calendars would no longer line up with the seasons, over time Christmas in the Northern Hemisphere would be during summer, the 4th of July would be in winter.

    Not a problem because calendars can be adjusted every few years so we don’t have winter in July

    Calendrers would progressively become inaccurate.

    Every 4 years the change of Seasons would move back ONE day on the Calendar

    The calendar would drift from the seasons by a day every four years and would be six months out after 730 years.

    Our calendars years would match the solar year even less exactly than they do now. Which is not necessarily a bad thing since all measuring units, including time units, are arbitrary. But it you want the seasons to start on the same day, or close to it, every year, you need leap years.

    The calendar year would be too short by about 5 hours 46 minutes, with the result that seasons would slowly float through the calendar.  Inn the sixteenth century the Pope was concerned Good Friday--Palm Sunday--Easter were occurring earlier, with the Spring equinox on March 11.  Having Christmas fall into Lent would be a bit confusing, so the reform governing century years (leap only if divisible by 400) cured the problem.  No leap years would hasten the problem, so instead of the Northern Hemisphere celebrating a white Christmas, for a few centuries it would have heat waves greeting those reindeer.

    every four years, the seasons would start and end a day earlier in the year

    "What would happen if leap years never existed?"

    In 91 years summer will have shifted back into spring, winter will have shifted back into fall, fall would be summer and spring would be winter.

    All that's happening with leap years is fixing the calendar to the point where it works for our world of days and years.  One day is one rotation of the earth around its axis.  One year is one rotation of our earth around the sun. This rotation does not work for the exact amount of days that we call a year (365).  Leap years are a rough correction for this.
