Problem Statement

Isabella has 66 coupons that can be redeemed for free ice cream cones at Pete's Sweet Treats. In order to make the coupons last, she decides that she will redeem one every 10 days until she has used them all. She knows that Pete's is closed on Sundays, but as she circles the 6 dates on her calender, she realizes that no circled date falls on a Sunday. On what day of the week does Isabella redeem her first coupon?
