From the product usage guide:
How Points Are Calculated on Usage Data
The VMware Service Provider Program Bundles are charged as per aggregated reserved RAM usage, and charging is done through a monthly point system where months can have the following number of days:
28-day months = 672 hours
29-day months = 696 hours
30-day months = 720 hours
31-day months = 744 hours
So for February you would be using 672 hours.
