Payments conducted on a banking holiday will not be processed until the next business day. For instance, if you pay on a holiday when banks are closed, you can expect it to be processed when the banks reopen. Additionally, if you initiate a payment over the weekend immediately preceding a holiday, that payment will be held until the next business day. This means that transactions may take longer to process during holiday periods, so it's advisable to plan accordingly if you require timely payments.
