Track array - calendar view

Thank you for your help. I have attached a sample document. What I am trying to do is match dates on the left to the dates on the top.

On teh left, there is a column for START DATE and one for END DATE. If the start date matches the date along the top, I want to put an "X" in the box and every box until it hits the END Date.

I hope this makes sence.

Thank you in advance for your help
