A few days ago I deposited my paycheck via Wells Fargo ATM. It was placed on a hold and said that I'll get half the money tomorrow (May 5) and the other half on the 13th. However, I checked my account and it still says its unavailable and "processing". Shouldn't it already be processed by now because Apparently I get half of it tomorrow? I'd call the bank about it but it's closed right now.

So today IS the 5th. Be patient. That half will probably be "made available" at the end of the day.

large deposits can take up to a full week to clear

It probably is processed, and your computer just isn't reading it right.

So call them tomorrow and ask for an explanation.
