Weekday Calculator

Calculating the day of the week for any given date is a handy tool for planning, event scheduling, and historical research. This capability spans across various applications, from academic to personal use.

Historical Background

The concept of weekdays dates back to ancient civilizations, which adopted a seven-day week structure inspired by celestial bodies. The calculation of the day of the week for a specific date has intrigued mathematicians and astronomers for centuries, leading to the development of various algorithms and formulas.

Calculation Formula

One of the simplest methods to determine the weekday is the Zeller's Congruence formula. However, for simplicity and broader accessibility, we use programming functions like Date.getDay\(\) in JavaScript, which abstracts the mathematical complexity and provides an immediate result.

Example Calculation

For instance, if you input "2024-02-21", the calculator will return "Thursday".
