Facebook group, the pair will be walking down the aisle on March 22, 2022.
A graphic on the page not only showed the wedding date, but also included Jeremiah and Hannah's name.
Earlier in January, Jeremiah shared with fans the exciting news of his engagement to Hannah as he posted various photos including one of them with their arms around each another.
He wrote: "She said YES!
"Hannah, getting to know you for the past year has been so incredible! I can’t even find the words to describe it. You are the best thing that has ever happened to me and I cannot wait to marry you. I love you!"
The Counting On alum added: "Thank you to everyone who helped make the day possible!! The Wissmann family and Jed & Katey went above and beyond to make it special."
In addition to their hugging pic, other snaps included Jeremiah on one knee while he proposed in the woods, as well as Hannah showing off her engagement ring.
