can i go to a church and just donate my 10% on any day?

cuz i get paid on mondays and rarely have money by sunday...im still in college and want to tithe but the urge to spend it on things i need like rent and food usually wins...but if i can tithe on monday and plan for that instead of trying to save it for sunday, it might work out better for me

If you choose to tithe you can do so any day of the week .

Yep

the Bible says pay with the first of your earnings, or something along those lines... meaning that the first thing you should calculate in when you get paid is your tithe.

And just set that aside or go do it right away.

Keep in mind that you don't have to tithe only to the church you go to, feel free to tithe anywhere in the church field in general as well. Helping someone with mission funds, sponsoring a child, etc... At least, this is the way I understand it.
