The Egyptians used the star Sirius, also known as Sothis, to predict the annual flooding of the Nile. The appearance of Sirius in the pre-dawn sky marked the start of the inundation season, which was crucial for agriculture in ancient Egypt. This celestial event was closely linked to their agricultural calendar and rituals.
The Egyptians new because every year birds called the Ibises would fly by shortly before the nile was going to flood. Also Egyptian priests' would study the sky has part of their religion. They noticed that a star now called Sirius would show before the Nile would flood. Based on that they created one of the world's first calenders. It had 365 days just like ours.
The ancient Egyptians predicted the annual flooding of the Nile River by closely observing the stars, particularly the heliacal rising of the star Sirius (Sopdet), which occurred around late June. This astronomical event coincided with the onset of the flood season, marking the beginning of the agricultural year. Additionally, they monitored the cyclical patterns of the river's water levels and seasonal changes, which helped them anticipate the timing and magnitude of the floods. These predictions were crucial for their agricultural planning and societal organization.
The ancient Egyptians relied on the annual flooding of the Nile River to determine the timing for spring planting. They observed the heliacal rising of the star Sirius, which coincided with the Nile's flood season, signaling the start of the agricultural year. This event typically occurred around mid-July, and as the waters receded, it indicated the optimal time for planting crops such as wheat and barley. Their calendar and agricultural practices were closely aligned with these natural cycles.

It is called Ursa Major.

Between the months of July and October, otherwise known as the Ankhet season.
Ancient Egypt needed to plan its events around the flooding of the Nile River. Its seeds had to be planted as soon as the flood waters receded. So they planned the calendar based on the annual flood. To make the date precise, they chose the date the star Sirius, or the Dog Star, rose at the same time as the sun. (Due to the wobble of the earth, called precession of the poles, it rose 3 months earlier 4,000 years ago than it does today. Like the Julian calendar, it would not be a good calendar to use today.)

The earliest Egyptian calendar was based on the moon's cycles, but the lunar calendar failed to predict a critical event in their lives: the annual flooding of the Nile river. The Egyptians soon noticed that the first day the "Dog Star," which we call Sirius, in Canis Major was visible right before sunrise was special. The Egyptians were probably the first to adopt a mainly solar calendar. This so-called 'heliacal rising' always preceded the flood by a few days. Based on this knowledge, they devised a 365-daycalendar that seems to have begun in 4236 B.C.E., the earliest recorded year in history.
Sirius
That is the Greek name for that star. The Egyptians called it Sopdet.
1200 BC. I think...
