why we still have “banking hours”

Question

Want to pay your bill Friday night? Too bad, the transaction will go through Monday morning.
In 2024, why, its not like someone manually moves money.

EDIT: I am not talking about BRANCH working hours, I am talking about time it takes for transactions to go through.

EDIT 2:
I am NOT talking about send money to friends type of transactions. I’m talking about example: our company once fcked up payroll (due Friday) and they said: either the transaction will go through Saturday morning our you will have to wait till Monday. Idk if it has to do something with direct debit or smth else. (No it was not because accountant was not working weekend)

Answer 1

There really is no good reason for it beyond banks in some countries not making any effort to implement such a system. In the UK, you can send bank transfers using the faster payments service introduced decades ago, and they will arrive typically within 30 seconds no matter what time of day or if it’s a holiday etc.
