BOI send payments to other banks each working day, i.e. 5 days per week. The cut-off for inclusion is around 17:00 each working day. All payments initiated after the cut-off today will be held for inclusion in the next working day's (i.e. Monday's) payments, even though the payer is debited there and then.
Today, before 17:00 = Tuesday
Today, after 17:00 - Wednesday
At times like Christmas and Easter, when there is a succession of bank holidays, the delay is extended.
