Project plans, leave entitlements, payroll cut-offs. The ChrysoKit Workdays Calculator counts business days between two dates, with custom weekends and a holiday list so it matches your office calendar.
Why use it
Calendar arithmetic in spreadsheets is easy to get subtly wrong. A purpose-built tool with weekend and holiday settings removes the guesswork.
How to use the Workdays Calculator
- Enter the start and end dates.
- Pick which weekdays count as weekends (Saturday and Sunday by default; pick any combination for non-standard regions).
- Add public holidays to exclude them from the count.
- Read the total workdays, weekend days, and excluded holidays.
Features worth knowing
Custom weekends
Pick any combination of weekdays as non-working. Some regions use Friday-Saturday weekends instead of Saturday-Sunday, the tool handles it.
Holiday list
Add public-holiday presets for several common countries, or type in custom dates to match your specific office calendar.
Live breakdown
Total workdays, weekend days, and excluded holidays show up together so you can verify the math at a glance.
Pro tips
- Different industries use different work weeks. The tool supports anything from a three-day to a six-day week.
- When estimating delivery dates, count workdays not calendar days. It matches how teams actually plan.
- Public holidays vary by country. Maintain a single list of dates and reuse it across projects.
Privacy first. The Workdays Calculator runs entirely in your browser. Nothing is uploaded.
Use the Workdays Calculator for project planning, leave estimates, and SLA windows. The math is small but the savings on rework are not.
