Job 1:4,13

I have seen several posts about Job's children celebrating their birthdays using Job 1:4,13 as proof. But out of the several translations that I read I don't see where it says it was their birthday being celebrated. The closest thing I saw was that it said "on their day". How does one come to the conclusion it was a birthday celebration?

Because Job 1:4 15 says:
And thine children were happy at Chucky Cheese

I just hate these new modern translations
