Each of us were only born in one month so what do we have to compare it to? 🤔
Other than having to deal with bad weather.... How can any month be bad?
We don't have any seasons that cause any disadvantages due to weather, so being the little child I am, I'll base my answer off of birthdays.
April and May are the worst months because it's exam times and no one has time to celebrate your Bday because of work or school stuff :((
