It seems as though there's even more to celebrate than usual this year for Michael Douglas and Catherine Zeta-Jones.

The longtime couple and parents of two both celebrate birthdays today, the Oscar winners having been born on the same calendar day, albeit 25 years apart, making him 71 and her 46.

But not only do these two Libras balance each other out on the astrological scale, their life together has happily evened out after a rough patch. Two years after spending the built-in family holiday apart, Zeta-Jones and Douglas are thoroughly back together after a "temporary separation" and have spent 2015 crisscrossing the globe together as a unit.

Which seemingly would make for a much nicer joint birthday party this weekend, right?

"We had a little bump in the road," Douglas acknowledged this past summer in Event magazine. "The problem in this business is that everything is so public."

The Ant-Man star added, "I love Catherine as much, more than I ever have. And hopefully the feeling's mutual...We worked things out—if both people want to work something out and make it better, you can do it. You can't do it if it's just one person."

Perhaps the odds are even better if you're each one half of the same birthday coin.

So in honor of their joint birthday, enjoy a trip down memory lane—from Chicago to Wall Street to Israel this past summer—with the couple's best pics through the years:
