Day Progress Calculator
See how much of today is over, live. Shows the percentage of the day elapsed, the current time of day, time since midnight, and time remaining until midnight.
How It Works
Formula
Variables, symbols and units
- Whole minutes elapsed since local midnight (00:00 = 0)
- Total minutes in a 24-hour day
- Share of the day already elapsed at the reference time
Calculation method explained
Leave the field blank and the meter tracks the current moment live, or enter a time to inspect it. The calculator measures how far the day has progressed from local midnight and divides by the 24-hour length of the day. Midnight reads 0% and 23:59 reads 99.9%; the current minute is still in progress.
Day progress is a one-step ratio against a fixed 24-hour day:
- Take the reference time: your live local clock when the field is blank, or the entered time otherwise.
- Count whole minutes since local midnight, where 00:00 = 0.
- Divide by 1440, the minutes in a day, and multiply by 100, rounded to one decimal.
- Derive the time remaining as the minutes left until the next midnight.
Frequently Asked Questions
Why does midnight show 0%?
The percentage counts elapsed time since 00:00. At exactly midnight no part of the day has passed yet, so it reads 0%. By the same logic 23:59 reads 99.9%; the final minute is still in progress.
Does it update live?
Yes. When the time field is left blank, the meter follows your device clock and ticks forward every second. Enter a specific time to freeze the view on that moment instead.
Which clock does it use?
Your device’s local time. The day runs from local midnight to the next local midnight, so the result matches the time you see on your own clock.
How is the percentage calculated?
It divides the time elapsed since midnight by the length of a full day (24 hours) and multiplies by 100. For example, 15:20 is 920 minutes into a 1,440-minute day, which is 63.9%.
