Hi! When editing my timeline, I had many timeline years and month change after I entered them, and then again after I hit save.

Steps to Reproduce

1. Select either "Create Historical Event" or Edit an existing one. 2. Enter or edit date. 3. Select anywhere else after entering the date. The date may now be different than the number entered. 4. Hit save changes. The date may now be different than the number entered.   This happened over half of the times I edited my timeline over the course of 3 hours.
