There are only 366 dates available. The Most widely used format is MMMDD (Example: Dec01).

These dates offer great utility and hold a special significance to people (ex.birthdates, holidays) and companies too.

There is a market here for these short dates which was sold out within the last few days. I have attached a few of the photos with statistics, as well as a google sheet which includes all of the IDs for you to easily add the custom filter on your site.

Thanks for your consideration.
