This tool helps you calculate the total time elapsed between two given dates and times.

## How to Use the Time Lapse Calculator

To use this time lapse calculator, follow these simple steps:

- Enter the start date and start time of the event.
- Enter the end date and end time of the event.
- Click the “Calculate” button to get the time lapse between the two dates and times.

## How It Calculates the Results

The time lapse calculator calculates the time difference between the start and end dates and times. It computes the difference and returns the result in a number of days, hours, and minutes.

## Limitations

The calculator assumes that both the start and end times are in the same time zone. It does not account for leap seconds or daylight saving time changes. Additionally, if the end date-time is earlier than the start date-time, the result will be negative and may not be meaningful.
