About HowManyDaysInYear.com Updated 2025
We’re a small, education-first site that explains calendars, leap years, weeks, weekends, and workdays in clear, simple language. Our goal is to answer your question fast and then show you the “why” with friendly examples.
Our Mission
Make date and time math easy for everyone — students, teachers, planners, and the simply curious.
- Clarity first: short sentences, plain words, and visual tables when helpful.
- Accuracy always: we follow standard calendar rules and double-check the math.
- No clutter: fast pages, minimal design, and no clickbait.
How We Calculate Facts
We rely on the modern Gregorian calendar and widely used conventions such as ISO week numbering (ISO 8601). Key rules you’ll see across the site:
- Leap years: divisible by 4 (yes), by 100 (no), unless also divisible by 400 (yes).
- Weeks in a year: 52 full weeks plus 1 day (common) or 2 days (leap). Some years have ISO week 53 due to numbering.
- Workdays: Monday–Friday before holidays; totals vary by the year’s starting weekday and local holidays.
Note: Holiday counts differ by country and year. We explain the method so you can adjust for your location.
Editorial Standards
- Review process: each page is drafted, fact-checked, and plain-language edited.
- Sources: we prefer primary standards and official calendars when relevant; when examples vary by region, we say so.
- Updates: pages include the current year where it matters (e.g., 2025) and are reviewed periodically for accuracy.
- Corrections: if you spot an error, email support@howmanydaysinyear.com — we fix mistakes quickly.
