The first and last day

Definition

A schedule counts only inside the run’s analysis window. With no analysis.windows the window is the observed period, so the first and last day count only part of the day. For whole days, set a window that covers them.

Read the observed boundaries

Suppose a declared schedule runs from 09:00 to 17:00 but the observed period on the first day starts at 13:00. Counting only inside that period leaves four hours of that day's schedule, not the full eight. That difference follows from the window, even though the calendar itself is unchanged.

Declare the period you intend to compare

The configuration reference shows an explicit analysis window:

analysis:
  windows:
  - {name: march, start: '2026-03-02', end: '2026-04-01'}

Choose boundaries that cover the whole days required by your question, then compare them with the schedule and source coverage. A wider window does not create missing work evidence. Review schedule_clipped_to_observed_period when edge-day schedule totals are smaller than expected.
