Everything below is calculated for 2010 specifically, and every layout on this page prints from the generator above.
About the 2010 calendar
There is no February 29 in 2010. A common year is exactly 52 weeks and one day long, which is why the year ends on the same weekday it began, and why every date in 2011 lands one weekday later than it does in 2010. Set against its neighbors, 2010 sits one weekday on from 2009 and one weekday short of 2011. 2009 started on a Thursday, 2010 starts on a Friday, and 2011 starts on a Saturday. If you want the arithmetic behind that, how many days are in a year covers it.
2010 carries the ordinary 52 ISO weeks. Week 1 is the week containing January 4, so the first days of January can still belong to the last week of 2009, depending on where they fall. Two months in 2010 spill into a sixth row on a Monday-start grid: May and August. That is where day cells get shortest on a monthly layout. Switch the week start to Sunday and the six-row months become January, May, and October instead, so the setting genuinely changes what prints. 261 days fall Monday to Friday and 104 at the weekend, before any public holiday comes off. See how ISO week numbers work if the numbering matters for your work.
The movable dates are the ones to check before printing anything: Easter Sunday falls on April 4, with Good Friday on April 2, Mother's Day on May 9, US Thanksgiving on November 25, Chinese New Year on February 14, Eid al-Fitr around September 9. Fixed dates do not move, but the weekday under them does. In 2010, Christmas Day is a Saturday, July 4th a Sunday, Halloween a Sunday. Christmas falling at the weekend is worth knowing early, because most countries move the public holiday to the Monday or Tuesday after it. Turning on holiday marking in the settings puts your own country's public days on the sheet instead of a generic list.
2010 has a single Friday the 13th, in August. January and October are that rare kind of month with five Fridays, five Saturdays and five Sundays, which only happens to a 31-day month opening on a Friday. And because the Gregorian calendar repeats, 2010 is grid-for-grid identical to 1999: same weekdays, same dates, same month layouts. A 2010 sheet will be right again in 2021. Only the dates that move, Easter and the lunar holidays, need checking again.
2010 holds 13 full moons, the first on January 1 and the last on December 21. Two of them fall in the same month, so January and March carries a blue moon. February gets none at all, which is only possible in a month shorter than the 29.53-day lunar cycle. The lunar month does not divide into the calendar year, which is why the moon dates shift even between years whose grids are identical, and why a moon phase calendar has to be generated for the year rather than reused.

2010 calendar questions
- Is 2010 a leap year?
- No. 2010 is a common year: February has 28 days and the year runs to 365. The nearest leap years either side are 2008 and 2012.
- How many weeks are in 2010?
- 52 by the ISO-8601 count, starting on January 4. In days that is 365, or 52 weeks and one spare day. Those spare days are why the weekday of a given date moves every year.
- What day of the week does 2010 start on?
- January 1 is a Friday, and December 31 is a Friday. Printed with the week starting on Monday, January shows four blank cells before the 1st. With a Sunday start, five.
- Can I reuse an old calendar for 2010?
- Yes, if it is from 1999. That year has the same weekday pattern and the same common-year length, so every date lands on the same day. The next year a 2010 calendar will be right again is 2021. Only the holidays that move need re-checking, which means Easter and the lunar dates.
- How many working days does 2010 have?
- 261 days fall Monday to Friday, and 104 at the weekend. Public holidays come off that 261 and differ by country, so switch holiday marking on and pick your country before you count out a contract or a notice period.
- How many full moons are there in 2010?
- 13. The first is January 1 and the last December 21. January and March holds two of them, which is where the phrase blue moon comes from. The moon phase calendar marks all four principal phases on the dates they fall.
- Which 2010 layout should I print?
- The yearly sheet puts all twelve months on one sheet for a wall. The monthly layout gives each month a full page and room to write in. The weekly pages suit time blocking. All of them print at A4 and US Letter, and the calendar types guide compares the rest.
