weird to have her birthday party so late?

Angelina • 26. 9 years w/ my love. Married 💍 I'm an artist, nature lover, Crystal collector, mommy to 2 doggies and our babies, Lilliana 5/26/16 & Elena 5/10/19

my daughter is turning 2 may 26th. which is a Saturday. Saturdays are the only days the her dad and I dont work (he works 3rd and I work 2nd shift so we dont get much time to spend together as a family during the week) and we will be going to the zoo just the 3 of us. Sundays are his Mondays from working 3rd shift so he usually sleeps most of Sunday. The weekend after that we have his brother's graduation ceremony to attend and we also have to pay our rent so we decided to do her party for friends and family on June 9th. which is 2 weeks after her birthday. I didnt think it was that weird but his parents were making negative comments about it and kept asking me why I had it planned for that date and that it was "weird" and "didnt make any sense" 🤔🤔 is it weird???
