Pro Tips for Accurate Calculations:
Country Variations: Weekend days vary by country (e.g., Friday-Saturday in Middle Eastern countries). Regional Holidays: Some holidays are regional rather than national - use custom holidays for these. Partial Business Days: For precise SLA calculations, consider partial days when start/end times matter. Recurring Events: Set custom holidays as recurring for annual events like company anniversaries.
