The page features a calculator that can determine the day of the week for a given date. The user simply needs to enter the date in the format specified and the calculator will use a mathematical algorithm to determine the corresponding day of the week.
This tool can be useful for a variety of purposes, such as checking the day of the week for historical events, planning schedules, or simply satisfying one's curiosity.
However, with the recent upgrade to the website, this tool has become somewhat obsolete. The date input field now automatically displays the corresponding day of the week, making the calculator's main purpose redundant.
