週末を除いた、2つの日付の間の稼働日数をすばやく特定します。
In the professional world, calendar days are often less important than 'working days.' Most business contracts, project timelines, and delivery guarantees are based on Monday through Friday, excluding weekends. Calculating these manually across multiple weeks or months is tedious and high-risk, as it's easy to lose count. Our Working Days Calculator is a specialized tool designed for project managers, HR professionals, and freelancers. It strips away the Saturdays and Sundays to give you an exact count of the productive days available within any given date range, helping you set realistic deadlines and manage expectations.
使い方
This tool iterates through every day in the selected date range. For each day, it checks the 'day of the week' property. If the value corresponds to a weekday (Monday through Friday), it increments the counter. This 'brute-force' but precise method ensures that leap years and irregular start/end days never cause a calculation error.
計算式
Sum(Weekdays) between Date₁ and Date₂
Calculation Examples
1. **Standard Week**: From Monday to the following Friday is **5 working days**.
2. **Two Week Span**: From a Monday to the Friday of the following week is **10 working days**.
3. **Over Weekend**: From a Friday to the following Monday is **2 working days** (the Friday and the Monday).
Why use this tool in your daily life?
Realistic project management. This service ensures your schedules are grounded in business reality, preventing the over-commitment that occurs when weekends are mistakenly included in planning.
