What year has the same days and dates as 2011?

2022 will be the next time a "2011 calendar" will occur. 2016 is a leap year and only March to December were identical to 2011. 2011 began on a Saturday but 2016 is a leap year that began on a Friday, therefore - because of the leap day - 2017 began on a Sunday (not Saturday) and the next time a calendar from 2011 can truly be used will be in 2022, since 2022 will be the first year to start on Saturday since 2011.
