Option writers:

As you plan your buy/writes, make sure you know that the interval between March and April as well as from April and May is 4 weeks each. (Third friday of each month to the next).

The interval is usually 5 weeks. That will definitely explain lower prices (less premium) for out of the money options as there is 1 week less time and time value than normal.

On a percentage basis, that could be as much as 20%, or 1/4 point, the way the MM's think...
