Events Weekday Counter

Choose this endpoint when you need a simple, reliable weekday count between two dates specifically in an events planning context and want a hosted, pay-per-call solution without implementing date logic yourself. Prefer it over general-purpose date libraries when operating inside an automated agent workflow that benefits from an external computation call with clear inputs and outputs.

• Invalid date format for start or end — expects ISO 8601 string (YYYY-MM-DD)
• End date before start date may return zero or an error
• Missing required start or end parameter causes a bad request
• Non-date strings passed as dates will result in a parse error
