Technically, that will depend on where you're located in your time zone,
but it's going to be within a week either side of February 11.
Also by the way ... since the change is about 4 minutes earlier per day,
it might not be exactly 8 PM. The transit closest to 8 PM could be any time
within about 2 minutes of 8 PM either way ... and then 4 minutes earlier on
the next night.
The first recorded discovery of a nebula was made by Galileo Galilei in the early 17th century. He observed the Orion Nebula through his telescope on the night of January 26, 1610.
The moon that crosses the meridian at 9pm will depend on the specific date and location. You can use a planetarium app or website to determine which moon will be crossing the meridian at that time for your location.
The 180th meridian or antimeridian is used as the basis for the International Date Line because it for the most part passes through the open waters of the Pacific Ocean separating the east and west hemispheres.
The Moon crosses the local meridian at its highest point in the sky, which occurs roughly around the time it is full. However, because the Moon rises and sets about 50 minutes later each day, the exact time it crosses the meridian varies daily. Generally, it happens approximately 12 hours after the Moon rises. To determine the exact time for a specific date, you can refer to a lunar calendar or an astronomical almanac.
The imaginary line 180 degrees east and west of the Prime Meridian is called the International Date Line. Crossed from west to east, the date moves back by one day.

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 International Date Line roughly follows the 180th meridian.
The international date line is a meridian. It is also known as the Greenwich Meridian .

Orion is not one of the 12 zodiac signs, so there is no date to be born on to be an Orion. It is near both Taurus and Gemini in the night sky.
It roughly follows the meridian of 180° longitude.
The Prime Meridian is a line of longitude (0°). It goes through every north or south measurementbetween the north pole and the south pole, and no other lines of longitude cross it.
The second name for the prime meridian is the international date line
