After 20 years, Chick-fil-A is retiring its Cow Calendar.

"Congratulations are in order as the Cow Calendar has reached retirement age -- in cow years, of course," the fast-food restaurant said in an email sent to Chick-fil-A customers.

The company said there is no need to fear, though, because the Cow's commitment to "celebrating together, spreading joy and having fun is only getting stronger." The Cows are ready to meet more people in person instead of simply starring in the calendar.

Chick-fil-A said they are upgrading their Chick-fil-A One app experience to offer more chances to redeem free food rewards.

"Very soon, you'' have a lot more chances to redeem delicious food free food rewards using the new-and-improved Chick-fil-A One," the email continued.

The calendar will say goodbye at the end of the year.
