Use your own title/description for an event
I think that an easy way to customize an event, without having to persist the details per user, would be to use query parameters to customize the event. For example, if I wanted to create a countdown to the Anthem 5K Fitness Classic, a road race in Louisville, KY and the start of the Louisville Triple Crown of Running, I could specify the following URL:
This would display the countdown as it does today, but would display the specified description as well. I am sure that other query parameters could be specified to expand the possibilities.
Custom title. Days to "custom text".
Thanks developers, I am moving cities and counting days with this page.

The ability to pass in text to be displayed on a countdown page
e.g. https://days.to/20-february/2017?event="My Birthday"
There could then be a simple form to 'create' the page link (calendar popup, text entry box and drop down for event type, maybe a small display of the theme example when you choose an option).
