A countdown timer uses a simple time subtraction principle.

Countdown Formula

Remaining Time = Target Time − Current Time

For duration-based countdowns:

Remaining Seconds = Total Duration − Elapsed Time

Where:

Target Time = End time set by user

Current Time = Present system time

Duration = Starting countdown length
