Hello.

Do not use dates in dash separated formats - they'll be interpreted in your local (client/browser) timezone, so you might end up in the prev/next day.
See here:

Hello, makes sense, but can that be added to the docs, because the dash separated formats shows in the docs.

A gotcha or warn would be great.

Thanks
