date is not defined?

[XBLDev]

It keeps telling me that date is not defined.

Error log:

Uncaught ReferenceError: date is not defined

DevTools failed to parse SourceMap: http://localhost:8080/js/dayz.es.js.map

I tried to pass a date prop when rendering the component that contains the calendar but doesn't work.
