The temple is open on some Mondays on which there are holidays. Monday the 19th is President's Day and so the temple will be open with the first session beginning at 7am. It will close for 2 years for extensive renovations on March 4, 2018.
The first Endowment is at 7 am
According to LDS tools, there will be sessions starting every half hour from 7:00 am to noon and the baptistry will be open from 8:00am to 2:00 pm, but you might not get into the baptistry without an appointment.
I thought the temple is always closed on Mondays.
