About the calendar
The September 2031 calendar above marks the days off (Federal holidays) in orange, with the weekdays they are observed on when they fall on a weekend, and the other holidays in light blue, as the year calendar does. Under Customize you can choose the country, the first day of the week and the kinds of holidays marked; the year calendar uses the same settings.
Click or tap a day to see its holidays, the sunrise and sunset at Columbus, the length of the day, the Moon's phase, its number in the year and week, the sign of the zodiac and how far it is from today. Printed from the browser, the calendar fills a landscape page.
