The year 2012 was a leap year, which means it had 366 days instead of the usual 365 days. Leap years occur every four years to help synchronize the calendar year with the astronomical year. Therefore, 2012 included an extra day, February 29.
Via astronomical measurements.
No, February has never had more than 29 days. In a regular year, February has 28 days, while in a leap year, it has 29 days. Leap years occur every four years to help synchronize the calendar year with the astronomical year. Thus, February's maximum length remains 29 days.
A year can be less than 365 days if it is a leap year, which has an extra day (February 29) added to keep the calendar year synchronized with the astronomical year. Leap years occur every four years, with the exception of years that are divisible by 100 but not by 400.

The real, or astronomical, year has a length of a little less than 365.25 days. To have a full number of days in a year, the length of the year is usually set at 365, and every 4 years, an extra day is added. Thus, on average, the length of the calendar year matches the astronomical year; an important astronomical event like the Spring equinox (for the Northern Hemisphere) will maintain its date - approximately - at March 20 or 21.The real, or astronomical, year has a length of a little less than 365.25 days.

It takes about 365.24 days for Earth to orbit the sun, while our calendar year has 365 days. It would take around 4 years for the calendar year to drift one day out of line with the astronomical year, resulting in the need for a leap year.
There are typically 365 days in a year. However, in a leap year, which occurs every four years, there are 366 days. Leap years include an extra day, February 29, to help synchronize the calendar year with the astronomical year.
The shortest month of 1988 was February, which had 29 days because it was a leap year. Leap years occur every four years, adding an extra day to February to keep the calendar year synchronized with the astronomical year. Thus, February 1988 had an extra day compared to the usual 28 days in non-leap years.
There are typically 365 days in a year. However, in a leap year, which occurs every four years, there are 366 days. Leap years include an extra day, February 29, to help synchronize the calendar year with the astronomical year.
