Donald Trump was sworn-in as President of the United States three months ago -- on January 20, 2017. On Saturday, April 29, reporters, the general public, and Trump himself will mark his first 100 days in office. But many Americans and people overseas may be wondering: what is so special about a president’s first 100 days? The short answer is that nothing is very special about it. A president’s term is four years, or 1,461 days. So 100 days is just a small percentage of that time. In fact, many observers point out that the major issues earlier U.S. presidents faced often came much later in their terms. For example, George W. Bush had been president for more than seven months when terrorists attacked the United States on September 11, 2001. But Americans still use a president’s 100-day mark as a time to consider how the administration is doing, and whether things have changed. Over the next few days, you will hear many officials and reporters commenting on how well Trump has performed as president.
