And, indeed, the 13th of this month falls on a Friday. It's the year's lone Friday the 13th. In the leap year 2020, there were two Friday the 13ths (March 13 and November 13, 2020). In the year 2023, there will be two Friday the 13ths (January 13 and October 13, 2023).
There are two types of leap years: common and anomalistic. The year 2100 is an exception because it is not a multiple of 4 nor 100 but it is a multiple of 400 (years). Therefore, it is an anomalistic year. All other years are common years.
Anomalistic years occur every four years or more that is not a multiple of 400. If it is a multiple of 400, then it is a common year. For example, 2004 was not a multiple of 400 so it was an anomalistic year. 2016 was a multiple of 400 so it was a common year.
Here are some other examples of anomalistic years: 2020, 2024, 2028, etc.
The day of the week for which any date occurs second time is called its "second day". March 2nd is the second day of March, April 2nd is the second day of April, and so on. So, March 13th is also the second day of March.
Friday, March 13th is called "the 13th of March" or just "13th March".

In addition, Friday the 13th will never fall on a Tuesday in any year.

The second of two Friday the 13ths in 2020 occurs on November 13, 2020. Every calendar year, there is at least one Friday the 13th and a maximum of three Friday the 13ths. The last time we only had one Friday the 13th in a calendar year was in May 2016, and the next time will be in August 2021.
There are two factors that determine when a Friday the 13th will occur. First, there is the Friday the 13th holiday which is fixed on November 13 each year. Second, there is the weekly repeating pattern of negative numbers followed by positive numbers within the day of the week column. This means that every seven weeks has a Friday the 13th, starting with Monday, January 13, 2000.
In general, Fridays the 13th are considered an unlucky day because they are believed to bring about the end of something or to mark a beginning of trouble.
However, not all people believe this to be true. Some say that because it's a recurring phenomenon, there is no reason why these days should be any more unfortunate than any other day.
The term "Friday the 13th" first appeared in the United States in 1919 when newspaper editors noticed that many people were not buying paper on that date. They assumed that this was because it was an unlucky day and so printed fewer articles about events that were happening worldwide then than usual.
