# Martin Luther King, Jr. Day was established in 1986, so the first presidential inauguration to be affected was
# George Bush I on Jan 20, 1989. King's birthday was the 15th, but we celebrate it on the 3rd Monday of each January.
# So, to me, the interesting days would be when MLK is on the 19th, 20th, or 21st.

# Let's go until the year 2089, just to get a full 100-year period since MLK started.
