Hi Mark,
Payments are always later on a bank holiday as the banking system clearinghouse will process payments one day later than usual. In this case it will be Tuesday, for example if you sent money to someone else today, it will not show in their account until Tuesday.

In answer to your question, I’m afraid there isn’t a way you can check, if you look at your statements it will give you a rough idea. The only exception to this is bank holidays for the reasons I’ve explained.
Regards
Glenn
