| Entry | minutes | Cumulative minutes |
|---|---|---|
| 1 | 20 | 20 |

Each entry is a duration in minutes, not a clock time. Overlapping sessions are not detected.

How to use Exercise Time Adder
- Enter session lengths in minutes.
- Calculate, then explore session lengths, session share, cumulative time.
- Read the worked example and calculation limits before applying the result.
Worked example
20 + 30 + 15 = 65 minutes.
Formula, accuracy & limitations
Total time = sum of the entered session lengths.
Each entry is a duration in minutes, not a clock time. Overlapping sessions are not detected.
Calculations use your inputs. Main numeric values show up to six decimal places, percentages up to two, and chart labels up to four. Time results use hours, minutes and seconds. Very small nonzero values use scientific notation.
Add session minutes without clock-time confusion
Enter durations such as 20, 30 and 15. A value of 30 means thirty minutes, not 00:30 on a clock. The list accepts commas, semicolons or separate lines and preserves the order you enter. Blank entries are skipped; zero or negative sessions are rejected so the count reflects actual positive durations.
Read total time and each session’s contribution
The result adds every session once. Session bars compare minutes, the donut shows each session as a percentage of the total, and the cumulative view shows how minutes build across your list. The hours-and-minutes display is a different format of the same total, not another exercise estimate.
Check overlapping sessions before adding
The calculator cannot identify overlapping workouts or duplicate entries. If one recording includes a warm-up that another recording also counts, remove the repeated time yourself. Sessions are numbered in input order; they do not imply dates or a weekly target.
Frequently asked questions
Can I enter hours and minutes such as 1:30?
Enter decimal minutes in this list. For one hour thirty minutes, use 90. For a 1 minute 30 second session, use 1.5. Clock notation such as 1:30 is rejected to avoid silently interpreting it the wrong way.
Do commas and new lines work together?
Commas, semicolons and new lines separate sessions. For example, 20, 30 followed by a new line and 15 adds three sessions for 65 minutes. Blank entries are skipped.
Does the total remove overlapping workouts?
No overlap detection is performed. Each entered duration is added once. Remove duplicate recordings or repeated warm-up time before calculating.
What is the difference between the chart views?
Bars compare individual session minutes, the donut compares their shares of total time, and the stack shows how those contributions make up the total. The charts all use the same entered session list.
