Betelgeuse is a star, not a planet, so it does not have a day. We have a day and night because at times we are facing or not facing our star, the Sun. Planets have days and nights as they rotate, but stars do not.
Betelgeuse is expected to go supernova within the next 100,000 years, although this estimate has a wide margin of error. When Betelgeuse does explode, it will briefly outshine the moon in our night sky and likely be visible during the day.
Betelgeuse does not actually rotate like a solid body, as it is a supergiant star with an irregular shape due to its strong pulsations. It is estimated that Betelgeuse has a rotation period anywhere from tens to hundreds of years.
