Student ProjectHi! I'm a student developer building Calculat in my spare time. I was tired of searching for basic math tools and having to click through 10 spammy popups, loan ads, and cookie trackers.
I keep this website 100% free, private, and ad-free. If this helped you with your homework, project, or finances today, bookmarking this page or telling a friend helps me keep building more free tools!
A weeks calculator translates multi-week intervals into equivalent calendar days, working hours, and decimal months. It is widely used by expectant mothers tracking 40-week gestation milestones, fitness coaches planning 12-week transformations, and educators organizing semesters.
D = W \cdot 7 \quad ; \quad H = W \cdot 168 \quad ; \quad M \approx \frac{W}{4.34524}Each week has exactly 7 days (168 hours). The average calendar month comprises 30.4375 days / 7 = 4.34524 weeks.
Scenario: A full-term human pregnancy is typically 40 weeks.
40 weeks × 7 days/week = 280 calendar days.
280 days × 24 hours/day = 6,720 hours.
40 / 4.34524 ≈ 9.2 calendar months.
There are exactly 84 calendar days in 12 weeks (12 × 7 = 84).
An average Gregorian calendar month has 4.345 weeks (365.25 days ÷ 12 months ÷ 7 days).
A standard year has 52 weeks and 1 day (52.14 weeks). A leap year has 52 weeks and 2 days (52.28 weeks).
Obstetricians calculate pregnancy from the first day of the last menstrual period (LMP), which spans 280 days or 40 weeks.
Count calendar days, business days, and weekends between any two dates with custom end-date inclusion.
Project future dates by adding months or calculate total elapsed months between two calendar dates.
Add or subtract days, weeks, months, and years from any date or calculate the exact duration between two dates.
