Resource Calendar: What It Is and How to Use It

Quick answer

A resource calendar shows when each resource is actually available — people, equipment, rooms; the calendar that turns planning into arithmetic.

What it contains

Working days, holidays, vacations, part-time, equipment availability — the real capacity.

Why it matters

Plans built on ’40h/week’ fail on actual calendars — the difference is the vacation nobody knew about.

Building it

Per resource: availability windows + exceptions — the calendar is part of the plan.

Keeping it

Holidays, part-time changes, new hires — the calendar ages; maintain it.

Bottom line

A resource calendar shows when each resource is actually available — people, equipment, rooms; the calendar that turns planning into arithmetic.
