Actually no one really knows. The montrer has a shifting timeline anyway which is why Maggie doesn't grow older.
But hmm Homer & her did meet in High School, which means they would only be few years apart in age, and they did attend their high school reunion together, but Homer was left back a grade ou so a bunch of times.
IT DEPENDS ON THE SEASON AS toi ALREADY KNOW THE KIDS NEVER AGE BUT, HOMER DOES GET A an OLDER ONCE IN A WHILE AS FOR MARGE I ONLY HEARD HER SAY 34 BUT, IT'S BEEN A WHILE SINCE HER AGE WAS MENTIONED SO I DON'T KNOW LOL! MAYBE WE SHOULD JUST COME UP WITH A APPROPRIATE AGE SINCE IT ISN'T REALISTICLY POSSIBLE TO STAY ONE AGE FOR MANY YEARS LOL! I DON'T KNOW JUST BEING GOOFY I GUESS!
