Weeks to Days Converter
Pregnancies are counted in weeks, rentals and training programs too — but appointments and itineraries need days. Converting weeks to days makes plans concrete: 12 weeks is 84 days, a 40-week pregnancy is 280 days, and a 2-week holiday is 14 days of freedom. One week equals 7 days, so multiply weeks by 7. The seven-day week is one of humanity's oldest continuous cycles, used for everything from work rosters to religious observance across cultures. The converter above works instantly both ways, the table covers 1 to 52 weeks, and the FAQs translate the week-counts people actually live by.
