Mathematical Logic Behind It
The calculator loops through every day between two given dates. Each day’s numeric value (from 0–6) is checked using JavaScript’s Date.getDay() method. Days with values 0 (Sunday) or 6 (Saturday) are excluded. The final count represents the total working or “business” days.
