Business Days Calculator

Count business days between two dates, excluding weekends and custom dates

Comma-separated, may be left blank

Note: This only excludes weekends and the dates you enter yourself, and does not include any country's public holidays — holidays differ each year and by industry, so we won't guess for you. When scheduling, please also enter local public holidays in "Additional excluded dates".

Instructions

영업일 계산기 사용 설명



기능 소개


특정 날짜 범위에서 실제로 일할 수 있는 영업일이 며칠인지 계산하여 일정 계획, 납기 기간 산정, 공수 추정에 도움을 줍니다.

사용 방법


  • 시작 날짜와 종료 날짜를 선택합니다(기본값은 이번 달 1일부터 오늘까지)

  • 토요일과 일요일을 제외하려면 「토요일, 일요일 제외」 체크를 유지합니다

  • 알고 있는 법정 공휴일을 「추가 제외 날짜」에 입력합니다. 형식은 `2026-01-01`이며 여러 개는 쉼표로 구분합니다

  • 결과 영역에 영업일, 자연일, 주말 일수, 추가로 제외한 일수가 함께 표시됩니다


    • 주의 사항


  • 여기에는 어떤 국가의 법정 공휴일 데이터도 포함되지 않습니다 —— 공휴일은 매년 달라지고 업종마다 다르므로 저희가 임의로 추정하지 않으며 직접 입력하셔야 합니다

  • 영업일은 자연일을 하루씩 판단하므로 연도와 월을 넘어가도 정확합니다

  • 모든 계산은 브라우저에서 완료되며 날짜는 서버로 전송되지 않습니다

    • ❓ FAQ

    Do the counted workdays include public holidays?

    No. The tool only excludes weekends and any dates you enter manually; it has no built-in holiday calendar for any country. For official scheduling, add local public holidays to "Additional dates to exclude".

    Why do I have to enter holidays myself?

    Public holidays vary by country and region and change every year. Rather than give you a list that may be outdated or inapplicable, we let you control it.

    Can it tell me what date falls after a certain number of workdays?

    Use it together with a date calculator: first get the total workday count here, then add the days in the date calculator, or estimate by subtracting the weekend days.

    The Difference Between JS Formatting/Minification and Manual Code Cleanup: Which Is More Suitable

    The difference between JS formatting/compression and manual cleanup comes down to automation versus human judgment. Formatting and compression are handled in bulk by tools according to rules—fast and consistent; manual cleanup is more flexible, suited to scenarios with special naming conventions or complex logic. For everyday development and debugging, use tools first and save human effort for the parts that truly need judgment. Understanding what JS formatting and compression means helps you decide when to use it and when to stop.
