Project Management
Project Duration Calculator
Estimate total project duration in days by dividing total work (tasks Γ average duration) by the number of tasks that can run in parallel. Use it for rough early-stage project planning, capacity-vs-deadline checks, or sprint capacity estimation in agile teams.
