What is a "Days of the Week" Calculator?

A Days of the Week Calculator is a tool that helps you determine which day of the week a specific date falls on. It can be used to find out the weekday for any given date in history or the future (e.g., Monday, Tuesday, etc.).

Why Use a Days of the Week Calculator?

• For planning: To find out what day of the week a future or past event will fall on (e.g., a birthday, meeting, or holiday).
• For historical research: To determine the weekday of significant historical events.
• For personal curiosity: Many people like to know which day of the week they were born, or which day of the week a specific event occurred in history.
• For scheduling: When scheduling appointments, events, or activities, it’s useful to know the weekday of a specific date.

How Does a Days of the Week Calculator Work?

• You enter a specific date (e.g., a birthday, anniversary, or any past or future date).
• The calculator then uses algorithms or functions (such as Zeller’s Congruence or Doomsday rule) to find the corresponding day of the week (Monday, Tuesday, etc.).
