Work Days & Holidays

The Work Days & Holidays page (Settings > Work Days & Holidays) manages two separate schedules in one place: the Deadlines schedule, which drives compliance leak-response due dates, and the Crew schedule, which tracks the days your crew actually works for pacing and workload projections.

Editing either schedule requires the Settings and Resource Management role. Users without the role can view the calendars but not change them. Changes save automatically.

A monthly capacity preview on the right side of the page shows the current month's working days and available crew capacity at a glance.

Deadlines Schedule

The Deadlines schedule is used when a rule's leak response deadlines are set as Business Days instead of Calendar Days. It defines which weekdays count as business days and which dates are holidays. Days that are not business days, and your configured holidays, are skipped when Chateau calculates business-day leak response deadlines.

This schedule affects compliance calculations only — it does not affect pacing or workload projections.

Unlocking the Deadlines Schedule

To prevent accidental changes to compliance-critical data, the Deadlines column is locked by default. Enable the Edit deadlines column toggle at the top of the page to unlock it for editing. The column re-locks automatically when you navigate away.

Work Week

The Work week section has a checkbox for each day of the week, Monday through Sunday. Checked days count as business days. A Monday–Friday operation would leave Saturday and Sunday unchecked, while a 24/7 operation might check all seven days.

At least one weekday must remain a business day — Chateau will not let you turn off the last one, because a business-day deadline could never resolve without it.

Holidays & Closures

The Holidays & closures grid lists each configured holiday with its recurrence spelled out in plain English (for example, "4th Thursday of November") and the date it next occurs. There are two ways to add a holiday:

Add US holiday — pick from a list of preset US federal holidays. Add custom holiday — define your own, using one of three types:

Recurring holidays apply automatically every year — you do not need to re-enter them.

How Chateau decides whether a date is a business day

A date counts as a business day only if both of the following are true:

• Its weekday is checked under Business Weekdays, AND
• The date is not one of your holidays.

Changes apply to future calculations only

Adding or removing business days and holidays does not recalculate deadlines that already exist. Leak response deadlines computed before your change keep their original dates; the updated calendar applies to deadlines calculated after the change.

For how response deadlines use Business Days versus Calendar Days, see the Rules Terms article.

Crew Schedule

The Crew schedule tracks the days your crew is working. It is used for pacing calculations, workload projections, and LSTAR targets — for example, showing how many working days remain in a monitoring period and what pace is required to finish on time. It does not affect compliance deadlines.

The Crew schedule is configured in the same Work week and Holidays & closures tables as the Deadlines schedule. Each table row includes both a Deadlines column and a Crew works / Crew off column — check the columns that apply to each day. For example, Christmas might count for both columns; a plant shutdown would check Crew off only.

The Month Preview on the right side of the page shows the current month's totals:

• Deadline business days — days that count for business-day deadline calculations
• Crew working days — days your crew is scheduled to work
• Effective for pace / LSTAR — crew working days after subtracting any Completion buffer days (see below)

Completion Buffer

Completion buffer (crew / pacing only)

The Completion buffer lets you set aside the last N working days of a period as a built-in cushion. Those days are excluded from pace, projections, and LSTAR targets — Chateau calculates pacing as if the period ends early. The buffer days are still workable for catch-up if the crew falls behind, but they do not count toward the pace target.

Configuration: Under the Completion buffer section, set:

• Reserve the last [N] working days of each [Period] — enter the number of days and choose the period (Quarter, Month, etc.)

Effect: The Month Preview shows two separate numbers: Crew working days (total scheduled days in the month) and Effective for pace / LSTAR (scheduled days minus any buffer days that fall within that month). For example, if you reserve the last 4 working days of each Quarter and 2 of those days fall in June, the month preview shows 22 crew working days and 20 effective days.

Buffer days are shown as a hatched pattern on the month preview calendar. The preview also shows a note explaining any difference between deadline business days and effective crew days — for example: "Projections built on deadline days alone would assume 2 more working day(s) than the crew plans against (incl. 2-day buffer)."
