Date Calculator

Calculating dates manually can often be confusing and time-consuming. Whether you need to find the number of days between two dates, determine a future or past date, or calculate age, doing it manually can lead to errors. A Date Calculator is a digital tool designed to simplify date calculations and provide accurate results instantly. It is especially useful for students, professionals, project managers, and anyone who frequently works with dates.

This project provides a user-friendly interface where users can input two dates or specify a date along with a number of days, months, or years. The calculator then computes the difference between dates, finds future or past dates, or calculates age and durations. It is highly useful for academic, business, and personal applications, helping users save time and avoid mistakes.

Objective

The main goal of the Date Calculator is to provide a simple, accurate, and fast tool for all date-related calculations. Specifically, it aims to:

• Calculate the number of days, months, or years between two dates accurately.
