international dateline
The transition line, often referred to as the International Date Line (IDL), serves as the demarcation point for calendar days. It is an imaginary line located roughly along the 180° longitude in the Pacific Ocean. Crossing the IDL from west to east subtracts a day, while crossing from east to west adds a day. This ensures that regions on either side of the line maintain a consistent calendar day despite the Earth's rotation.

The International Date Line is the imaginary line opposite the Prime Meridian that does not currently run through any nation. It is located opposite the Prime Meridian at 180 degrees longitude and serves as the transition line for changing calendar days.
The International Date Line is a fake line that runs through the Pacific Ocean. This line separates calendar days so that they do not overlap.
The International Date Line is an imaginary line on the Earth's surface that determines the change in calendar date when crossed. It roughly follows the 180° meridian and is used to mark the transition between consecutive calendar days. Crossing the date line from east to west results in gaining a day, while crossing from west to east results in losing a day.
The five extra days added to the Egyptian calendar were known as the "epagomenal days." These days were added at the end of the 12 months, each consisting of 30 days, to align the calendar with the solar year. They were considered a time for festivals and celebrations dedicated to the birth of the gods Osiris, Isis, Seth, Nephthys, and Horus. This period was seen as a time of transition and renewal in Egyptian culture.
The 180 degrees longitude is the International Date Line, which runs from the North Pole to the South Pole and serves as the transition line for calendar days. When crossing the line from west to east, you would either move one day forward; when crossing from east to west, you would move one day back.

To keep the calendar in line with the rotation of the earth.
Calendar days are every day on the calendar, including weekend days, weekdays, business days and holidays. So, for example, 10 calendar days after the 4th of a month is the 14th of the same month.
The line of longitude where one day ends and another begins is called the International Date Line. It roughly follows the 180° meridian in the Pacific Ocean and marks the transition between calendar days.
It takes about 365.24 days for Earth to orbit the sun, while our calendar year has 365 days. It would take around 4 years for the calendar year to drift one day out of line with the astronomical year, resulting in the need for a leap year.
