McDonald's is reviving its fried apple pies to mark the 250th anniversary of the United States.

The chain announced Tuesday that the fried apple pies return to most U.S. locations for a limited time beginning June 23. This is the first reintroduction in more than three decades.

Other fast food chains are also rolling out special treats for the milestone. Burger King introduced its Firecracker Cookie Pie with a sugar cookie crust and red white and blue star sprinkles. Sonic offers a red white and blue slush float for 2.50 dollars. Hardee's features an iced Star-Spangled Biscuit topped with red and blue sprinkles.

Here is a breakdown of McDonald's fried apple pies by the numbers:

- 1968: The year McDonald's launched both its fried apple pie and the Big Mac. Franchisee Litton Cochran from Tennessee created the rectangular pie served in a cardboard sleeve. The year featured the assassinations of Martin Luther King Jr. in Memphis and Robert F. Kennedy in Los Angeles along with Vietnam War protests and a new federal law banning housing discrimination.

- 1992: The year McDonald's switched to baked apple pies in most U.S. restaurants amid rising awareness of fat and cholesterol intake. The U.S. Department of Agriculture released its food guide pyramid that same year. Fried apple pies continue on menus in countries including Mexico Australia and China.

- 230: Calories in the baked apple pie which is 10 more than the fried version per the company site. This matches the calories in a cup of boiled lentils an almond Snickers bar or a grande coffee Frappuccino from Starbucks.

- 130: Members of the Facebook group titled Bring Back the Original McDonald's Fried Apple Pie.

- 170 million: American-grown apples McDonald's serves each year across its U.S. locations.

- 35: Height in feet of a giant fried apple pie installation on Route 66 in Joliet Illinois near McDonald's Chicago headquarters. This equals the height of a three-story house or certain palm trees. The display remains until July 4.
