Define a global query parameter to be used by any relevant router

I have a situation, where most of the data to be fetched from the server (database) is related to a date (YYYY-MM-DD) chosen by the user.

Is it possible to define a global "date" query parameter, which can be used by any relevant route? If no value for "date" is supplied, then the server will by default return data where "date" is today.
