Steven Sandoval#Calendar trivia: there are only 7×2=14 possible calendars. That figure is determined by the weekday the year starts on and whether or not a leap year occurs (i.e. common year or leap year).
2025 is a common year Wednesday calendar as were those of 1975, 1986, 1997, 2003, and 2014. So, if you have an old calendar from any of those years, you can bring it out and use it again!
