How to accurately do a MTD comparison year over year when current Year/Month has less days than the previous Year/Month?

[ambetts2]

So for example take a leap year where the current year may have 28 days and the previous year has 29 days. A MTD comparison will compare only up to 28 days?

Thanks in advance for any assistance.

No problem. See attached example.
