# Time Past Calculator

### Introduction

Reflecting on the passage of time is a common human experience. The Time Past Calculator provided here enables users to precisely determine the duration between a specified past date and the current date, expressed in years, months, and days. This tool can be useful for historical research, personal reflections, and more.

### Formula

The calculator computes the time difference between the specified past date and the current date, then breaks it down into years, months, and days. It leverages JavaScript Date objects and basic arithmetic operations to achieve this.

### How to Use

1. Enter the current year in the “Current Year” field (e.g., 2023).
2. Enter the current month in the “Current Month” field (1-12).
3. Enter the current day in the “Current Day” field (1-31).
4. Enter the past year in the “Past Year” field (e.g., 2020).
5. Enter the past month in the “Past Month” field (1-12).
6. Enter the past day in the “Past Day” field (1-31).
7. Click the “Calculate” button.
8. The calculated time past will be displayed in the “Time Past” field.

### Example

Suppose you want to find the time elapsed between January 15, 2020, and October 25, 2023. Enter “2023” for the current year, “10” for the current month, and “25” for the current day. For the past date, enter “2020” for the year, “1” for the month, and “15” for the day. After clicking “Calculate,” the calculator will display the time past as “3 years, 9 months, and 10 days.”
