This Saturday marks 100 days since Donald Trump took oath as the 45th U.S. president and he's planning on signing four new executive orders before the big day.

The orders include one calling for reviews of offshore drilling regulations and another on national monument designations on federal lands, as well an order to establish an "office of accountability and whistleblower protection" at the Department of Veterans Affairs.

The four new executive orders will bring Trump's total to 32 in his first 100 days, the most of any president since World War II, according to ABC News.

While Trump leads in most executive orders signed in the first 100 days of presidency, has he signed more orders overall than past presidents?

Every president in U.S. history has had a different way of handling executive orders. Some presidents have signed many more orders than others and the substance of those orders vary.

The Department of State began the Numbering of the Executive Orders in 1907 assigning numbers to each order, according to the American Presidency Project (APP), a non-profit and non-partisan online source of presidential documents hosted by the University of California, Santa Barbara.

The Federal Register Act in 1935 helped install a more thorough process for documenting presidential regulations. 

Today, all executive orders to date are published unless they hold no legal effect or general application, according to the APP. There are many unnumbered orders with estimates ranging from 1,500 to 50,000 but the true number is actually unknown.

Data from the APP shows Franklin D. Roosevelt signed 3,721 executive orders, averaging 307 orders a year. However, FDR had more time to sign more orders since he served four terms and spent more than 12 years in office.

Woodrow Wilson, Calvin Coolidge and Theodore Roosevelt also issued more than 1,000 total orders during their presidency.

In recent history, presidents haven't signed nearly as many executive orders.

Barack Obama signed a total of 276 executive orders while president, averaging 35 a year, the lowest yearly average since Grover Cleveland who served as the 22nd and 24th U.S. president in the late 1800s.

George W. Bush issued 291 executive orders, at an average of 36 a year and Bill Clinton signed a total of 364, averaging 46 a year.

If Donald Trump wants to become the president with the most executive orders under his belt before the end of his time in the White House, he has more than 3,000 orders to pen to gain that legacy.
