How to set expiration of a cookie at the end of the day (next.js)?

Question

I'm using react-cookies and I'd like to let a cookie expire at the end of the day (not after 24hrs or at the end of a session BUT at the end of the day).

Here's how I set the cookie:

setCookies("dailyCookie", {
    path: "/",
    maxAge: // should expire at the end of the day, 
    sameSite: true,
  });

I haven't found the right solution, yet (similar questions: set cookie to expire at the end of current day). Any help is appreciated! Thanks!
