Need help in identifying not-in-ascending order set of values

I need to identify the rows that have a set of values that are not in ascending order.
In the excel sheet attached below, i need to identify the months that have corresponding values in not-ascending order.
I manually changed the color of the few months for reader understanding purpose.
This is just a sample sheet, my original sheet has more than 10 thousand rows and I am not attaching that sheet here as I can't disclose the data.
