Formulas Explanations:

Calculating the Time Difference:

To determine how much time is left until the target date and time, we need to find the difference between the current time and the target time:

timeDifference = targetTime – currentTime

targetTime: The time the user inputs (in milliseconds since the epoch).
currentTime: The current time when the countdown is calculated (also in milliseconds).

Calculating Days, Hours, Minutes, and Seconds:

Once we have the total time difference in milliseconds, we can calculate the days, hours, minutes, and seconds remaining.

Days:

days = ⌊ timeDifference / (1000 * 60 * 60 * 24) ⌋

This formula divides the total milliseconds by the number of milliseconds in a day to get the total number of full days remaining.

Hours:

hours = ⌊ (timeDifference % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60) ⌋

This formula calculates the remaining hours by first getting the modulus of the time difference with respect to the number of milliseconds in a day, then dividing by the number of milliseconds in an hour.

Minutes:

minutes = ⌊ (timeDifference % (1000 * 60 * 60)) / (1000 * 60) ⌋

This formula calculates the remaining minutes using the modulus of the time difference with respect to the number of milliseconds in an hour.

Seconds:

seconds = ⌊ (timeDifference % (1000 * 60)) / 1000 ⌋

This formula calculates the remaining seconds by taking the modulus of the time difference with respect to the number of milliseconds in a minute.

Example Calculation:

Suppose the target time is set for December 31, 2024, 11:25 AM, and the current time is October 26, 2024, 12:00 PM.

1. Calculate the time difference: timeDifference = targetTime – currentTime
2. Calculate days: days = ⌊ timeDifference / (1000 * 60 * 60 * 24) ⌋
3. Calculate hours: hours = ⌊ (timeDifference % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60) ⌋
4. Calculate minutes: minutes = ⌊ (timeDifference % (1000 * 60 * 60)) / (1000 * 60) ⌋
5. Calculate seconds: seconds = ⌊ (timeDifference % (1000 * 60)) / 1000 ⌋

This process gives the user a complete breakdown of the time remaining until the specified date and time.
