Every month of 2011 as a printable table, with public holidays, ISO week numbers and the year's eclipses, moon phases and meteor showers.
2011 has 365 days, starts on a Saturday, is not a leap year, and runs to 52 ISO weeks. It runs from Saturday 1 January 2011 to Saturday 31 December 2011. There are 10 United States federal holidays in 2011, two of which fall at a weekend and are kept on a different day. Worth knowing: 1 January 2011 falls in week 52 of 2010, not in week 1 of 2011.

Wk ISO 8601 week number
Weeks start on Monday so that the week number in the left gutter applies to the
whole row. ISO 8601 defines week 1 as the week containing the first Thursday of
the year, which is why 2011 has 52 weeks and why 1 January is not always
in week 1.
Public holidays in 2011

Meteor showers
Peak nights drift by about a day between years, because the Earth meets each
stream at a fixed point in its orbit rather than on a fixed date. What
changes the view far more is the Moon, so we compute how much of it is lit
on the peak night of 2011.

2011 is not a leap year, so February has 28 days.
Years you can reuse this calendar for
These years start on the same weekday and have the same February, so the grid
above is identical. A 2011 wall calendar hangs again, unchanged, in any of them.
Public holidays computed from statute, cross-checked against
Nager.Date for every year it covers. Astronomical
