There are some issues that we are going to add one additional month of the year chart, so we have 13 months a year. But, actually, that is not true, so the answer to this question is no.
But back in 1902, Moses B. Cotsworth is presenting a proposal for calendar reform and it divides the solar year into 13 months of 28 days each. The proposals were known as The International Fixed Calendar or the Cotsworth plan. Though it was never officially adopted in any country in the world.
However, this proposal actually gains attention too. Even to promote the Cotsworth plan to reform the calendar we use right now there are some people who founded a community called the International Fixed Calendar League (IFCL) in 1923. This idea is also being supported by George Eastment, the CEO of Eastman Kodak Company, also he uses this calendar system on his company. But, finally the IFCL ceased after the proposal calendar plan failed to win approval in the League of Nations in 1937.
The answer is yes. 2020 is a Leap year. Which means we had 366 days instead of 365. This happens because 2020 is divisible by 4 also according to Earth’s orbit around the Sun, this year is a little bit longer.
Generally, we have a leap year every four years which is an easy pattern to remember. But, there are several things that need to be highlighted.

The solar year with 12 months of the year chart we use right now is based on Julius Caesar's calendar. At first, there are only ten months in the calendar while there are over 12 lunar cycles in a year. Then, two months were added to synchronize with the seasons. Those 2 months were January and February.
Julius Caesar’s astronomers also explain that the original fifth and sixth months were renamed as July in honor of Julius Caesar and August were renamed in honor of his successor. Both July and August were given 31 days to reflect their importance as Roman leaders.
