In accordance with the Turkmen national calendar, starting from August 12, anyone wishing to observe "Yaldyrak"—the brightest star in the Canis Major constellation (Sirius)—can spot it in the eastern sky just before dawn. This cultural milestone was reported in the Turkmenistan newspaper.

Turkmen folklore includes several proverbs highlighting this seasonal transition, such as "Night cools during Üçýyldyz, day cools during Yaldyrak" and "Once Yaldyrak rises, the gazelle thirsts no more." These sayings reflect traditional observations that following the peak summer heat, the appearance of Yaldyrak brings cooler air, evening dew to foliage, and a gradual reduction in daytime heat.

The star earned the name "Yaldyrak" due to its exceptional brightness compared to other celestial bodies. It shines in its current position until September 22. On September 23, it hands over its position to the "Mizan" (Libra) constellation—derived from the Arabic word for "scales"—marking the autumn equinox when day and night are equal in length.

The Yaldyrak period leading up to Mizan coincides with a vital phase for agriculture, particularly the development of cotton fibers in bolls. Sustained warmth during this timeframe ensures high-quality cotton yields across Turkmenistan.
