News 8 checked with the congressional research service and Library of Congress and found there is some precedence of presidents creating and moving holidays with a proclamation.  

In 1863, President Lincoln proclaimed Thanksgiving would fall on the last Thursday of November. Nearly 80 years later, President Franklin D. Roosevelt changed it to the second to last Thursday. Then in 1941, Congress made it a permanent federal holiday.
