Today the Cheesecake Factory celebrates National Cheesecake Day by offering half-price on its 30 different types of the sweet treat. The chain also debuts its red velvet cheesecake, and for the next year, it'll donate 25¢ from each slice sale to hunger relief charity Feeding America. Fingers crossed National Ice Cream Sandwich Day (August 2), National Waffle Day (August 5) and National Rice Pudding Day (August 9) yield such delicious discounts.
