1. Restore from your most recent backup which you should have made before installing a new module. ( Note:Drupal is not for amateurs, despite what they say. Drupal does not have professional governance, like say Wordpress, and that makes it relatively demanding for the inexperienced. With Drupal you really need to be sit next to a helpful pro for a year.)

2. Check that the version of PHP , Drupal, MySQL and the Date module are all compatible. This is work, BTW. If not compatible, then reinstall where necessary and cross your fingers.

3. Check for known issues by Googling something like or based on "Drupal 7 Date module". Drupal 7 is old and issues that have arisen with so-called compatible modules may be well-documented.
