Calendar tools
Printable calendars, week numbers, quarters, fiscal years and weekday finders. Each tool has its own page. It runs in your browser, and it keeps its inputs in the address bar so you can share the answer.
The tools
Printable month and year calendars, ISO week numbers, quarters, fiscal years, leap years, and weekday finders for dates like the third Monday of a month.
Calendar GeneratorA clean grid for any month, with week numbers down the side, public holidays marked, and a start-of-week that follows your part of the world rather than an assumption.
Printable CalendarBig cells, no colour, no site furniture — a month or a year on a sheet of paper, with holidays and week numbers, ready to pin up.
Yearly CalendarTwelve months side by side, with holidays marked, week numbers available, and the year's own facts — leap or not, how many days, which weekday it starts on.
Weekly CalendarSeven days with their dates, week number, and the hours of the day down the side — a week planner you can print or share as a link.
Daily PlannerA single day broken into hourly slots, with sunrise and sunset marked, the week number, and the day's position in the year.
Week Number CalculatorThe ISO week for any date, the US week beside it, the Monday-to-Sunday dates the week covers, and how many weeks the year has.
ISO Week CalculatorA date to its ISO week-date form and back — `2024-W29-2` — with the ISO year, which is not always the calendar year.
Fiscal Year CalculatorThe fiscal year for any date, on whichever start month your organisation uses — with the year's own start and end dates and how far through it you are.
Fiscal Quarter CalculatorQ1 to Q4 on your fiscal calendar, the quarter's dates, how many working days it holds, and how far through it today is.
Quarter FinderThe calendar quarter for any date, its start and end, how many days it has, and how far through it you are — plus the same for the next four quarters.
Leap Year CheckerThe answer, the rule that produced it, the next and previous leap years, and the century exceptions that catch people out.
Day of Week CalculatorThe weekday for any date, past or future, plus its week number, day of the year, and which weekday that date falls on in the surrounding years.
Nth Weekday CalculatorThe date of the nth weekday of any month — third Monday, last Friday, second Tuesday — which is how most public holidays and most recurring meetings are actually defined.
Calendar Week FinderEnter a week number and a year, get the seven dates it covers — and the reverse, a date to its week — with both the ISO and US conventions.
