Add Canada Federal Working Days
Adds or subtracts dates using Canada federal general holidays and a Saturday/Sunday baseline; schedule-dependent substitute days remain unresolved.
When to use
You need a deterministic baseline offset for a federally regulated-employer calendar in 2026-2027.
Do not use when: You need a provincial, private-employer or schedule-specific substitution result.
Example user requests
- Add five Canada federal working days after 2026-09-28.
Formula
move one day at a time; decrement remaining only when Canada federal status.is_working_day=true
Skip the CLDR CA weekend baseline and actual Canada general-holiday dates; do not infer substitution.
