The date on which Betelgeuse will be on the meridian at 12 midnight depends on your location and the current date. You can check a star chart or astronomy app for your specific observing location to determine when Betelgeuse will cross the meridian at midnight tonight.
The Midnight Meridian refers to the line of longitude directly opposite the Prime Meridian, marking the halfway point between the International Date Line and the Prime Meridian. It is where each calendar day begins.
No, the prime meridian and the International Date Line are two different imaginary lines on Earth. The prime meridian is the line of longitude at 0 degrees, dividing the Earth into Eastern and Western Hemispheres. The International Date Line, on the other hand, runs mostly along the 180th meridian and marks the change of one calendar day to the next.

The day begins at the International Date Line in the Pacific Ocean, located roughly opposite the Prime Meridian. This imaginary line marks the boundary between two consecutive calendar days. When it's midnight at the International Date Line, the day officially starts there.
not sure what is up with all that^ but from the north pole to the south pole on one side of the world the international date line is the international date line. On the other side of the world The international date line is the prime meridian

Midnight.
The expected date of the Betelgeuse supernova event in 2022 is uncertain and difficult to predict with precision.
No. The "Prime Meridian" (Greenwich Meridian) is 0° longitude and runs through Greenwich, England, western Europe, and Africa. The International Date Line is on the other side of the world, at 180° longitude (east or west is the same line), and marks the start of each new calendar day. It is midnight at the Date line when it is noon at the prime Meridian. The actual line has detours to accommodate Russia, the Aleutians, and New Zealand.

The International Date Line roughly follows the 180th meridian.

The international date line is a meridian. It is also known as the Greenwich Meridian .
The International Date Line is 180 degrees longitude. By international agreement, the 180th meridian, halfway around the world from the Prime Meridian, has been selected as the line from which each new day will begin. Between any meridian where it is midnight and traveling to the east through all the meridians where it has already been midnight up to the International Date Line, it is the new day. The International Date Line is somewhat irregular, since the 180th meridian goes through countries and islands.The Date Line has been moved to the east or west of these places to avoid dividing a country into two different days. 180 Degrees.
The term "meridian" means "midday" or noon.The original definition of the Prime Meridian placed it at the "center" of the day, or noon, when the Sun could be determined as "directly overhead" at some point along the 0° meridian. This meant that midnight, the division between days, was at the 180° meridian, or "International Date Line", when it was noon in Greenwich. At that point, all points on the globe are marking the same calendar day.Because the Sun arrives overhead earlier east of the Prime Meridian, the time there is already after noon that day. Points west of the Prime Meridian will have their noon later that day, so they are "earlier" in the day.The terms "ante meridiem" (A.M. before noon) and "post meridiem" (P.M. after noon) follow the same convention. When it is afternoon at the Prime Meridian, a new day begins at the Date Line and "moves west" with the passing hours. Except at midnight, the Date Line will indicate a "day later" to its west than to its east.
