In this guide, we’ll explain what a date calculator is, how to use it, and why it’s so useful.
🔹 What is a Date Calculator?
A Date Calculator is an online tool that lets you find the exact difference between two dates. It calculates the duration in years, months, days, and even totals like hours, minutes, and seconds.
