Workday Progress Calculator

See how much of your workday is over, live. Set start and end times to see percentage elapsed, time worked, and time left until the work window ends.

How It Works

Formula

\text{percentComplete} = \frac{\text{now} - \text{start}}{\text{end} - \text{start}} \times 100

\text{timeLeft} = \text{end} - \text{now}

Variables, symbols and units

$\text{now}$: The current time, or the time you entered
$\text{start}, \text{end}$: Your configured workday start and end times

Calculation method explained

Set your start and end times. The calculator measures how far the reference time has progressed from start toward end and shows it as a percentage, along with time worked and time remaining. It treats the workday as one continuous time window.

Frequently Asked Questions

Does it update live?

Yes. When the time field is left at now, the meter follows your device clock and ticks forward every second. Enter a specific time to freeze the view.

What if it is before or after work?

Before your start time the meter reads 0% and shows the full window ahead. After your end time it reads 100%.

Does it account for breaks?

No. The percentage covers the full interval from start to end. Breaks, split shifts, payroll rules, and overtime are not modeled.
