What is this calculator?
Sitting time here is desk hours plus a seated commute. We add them and sketch one stand-up reminder for each seated hour, with five minutes if you take that break. It is a posture diary, not a blood-clot diagnosis and not a workplace assessment.
How it works
- Enter hours at a desk or in meetings where you sit.
- Add seated commute hours. Walking or cycling commutes can stay at zero.
- Read the seated total and the stand-up sketch. Use it as a nudge, not a target you must hit.
Common questions
What is the sitting time calculator?
It adds desk and commute sitting and shows hourly stand-up prompts. It cannot see your job or your health.
Does the sofa count?
Only if you include it. Many people log the workday here and treat the evening separately.
Is sitting dangerous?
Long sitting is discussed as one habit among many. This page does not diagnose risk. Moving a bit more is the useful next step.
What should I do in a break?
Stand, walk a corridor, or step outside. The work break planner maps focus blocks if you want a clock.
