Count the exact number of days, weeks, and hours until any future date — Christmas, New Year, a birthday, vacation, exam, or any personal milestone. Also works for past dates.
We take today's date at midnight and subtract it from the target date at midnight, giving whole days. Weeks are the floor of days divided by 7, and hours multiply total days by 24.
