Calculate count days

time.count_days

ProductionBounded custom (Class B)Deterministicstrictinstantv1.0.0

No network

Overview

Perform deterministic bounded count days from explicit ISO dates and an immutable caller-supplied calendar, returning deterministic receipt fields without wall-clock, locale, network, or inferred-holiday state.

We provide a bounded calendar result so you receive explicit version receipts.

Reliability

CALENDAR_INPUT_INVALID means dates, calendar, convention, or bounds are invalid; correct the closed request before retrying.

Context footprint

One call replaces prompt date loops. A successful call costs 1 execution credit.

When to use it

When you hold two ISO dates and an explicit includeStart/includeEnd pair and need the counted calendar-day span.

Avoid when the span must skip weekends or holidays — use time.business_days_between.

Scope

Note

Perform deterministic bounded count days

Non-goals
