Today we're celebrating Jane's birthday in Bath at the Jane Austen Centre and on the streets of the city.
At the Centre we been performing traditional carols, giving out Cassandra Austen's recipe plum pudding and mulled wine and generally having a bit of fun on this special day.
Have you done anything for Jane Austen Day? Let us know.
We've been asking members of the public if anyone knows what day it is. The results are great and you can see a short film we've made below.
