I am a night owl. I like to stay up late at night and sleep during the day.
Night owl (person)
A night owl, evening person or simply owl, is a person who tends to stay up until late at night, or the early hours of the morning. Night owls who are involuntarily unable to fall asleep for several hours after a normal time may have delayed sleep phase syndrome. 
The opposite of a night owl is an early bird – a lark as opposed to an owl – which is someone who tends to begin sleeping at a time that is considered early and also wakes early.

I will get up each morning as the sun rise; at night, I shall sleep late. (Or just: "In the morning I will get up early; at night I will sleep late." See.) When I realize that time is passing me by and cannot be turned back, and that I am getting older year by year, I will especially treasure the present moment. (See for the following.)
