When does that 180 day time frame end?

On January 21st, when the ACHDNC recommended to Secretary Sebelius that SCID newborn screening be added to the core panel of diseases which are recommended for all states, a clock began ticking.  She has, by law, 180 days to either recommend SCID newborn screening or send it back to the committee.  I was recently wondering at what point that 180 day time frame would end, so I looked up what would be 180 days after January 21st.  According to http://calendarhome.com/ it should be July 20th.  So I’ve decided to put up a ticker to help remember that date.
