With over 30 immediate family members on the Duggar family tree, the Duggars' birthdays must fill up a whole calendar. After all, there are only 52 weeks in a year — and with grandkids always on the way, that schedule is only going to get more full over the years. Speaking of, Jinger Duggar and Jeremy Vuolo just welcomed their daughter Felicity, and Joseph Duggar and Joy-Anna Duggar had their own babies earlier this year. We can't keep up with this family — and god save the poor people who've never even hard of them.

It won't be long until we can't go a single week without a Duggar to celebrate — but hey, we'll take the excuse to eat cake pretty much any day. It doesn't matter that we're not actually planning a trip to the Duggar's house to join the party (although, let's be honest, Duggar parties aren't exactly barrels of laughs anyway). Invite or not, we'll blow out a candle and treat ourselves to some dessert regardless. Want to know when to celebrate? Check out all the birthdays on the Duggar family calendars below.
