Hanlu

The traditional Chinese calendar divides a year into 24 solar terms (節氣). Hánlù, Kanro, Hallo, or Hàn lộ is the 17th solar term. It begins when the Sun reaches the celestial longitude of 195° and ends when it reaches the longitude of 210°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 195°. In the Gregorian calendar, it usually begins around October 8 and ends around October 23.

 * 鴻雁來賓, 'The guest geese arrive' – Geese which completed their migration in summer were considered 'hosts', and the later-flying ones as 'guests'. This pentad can also be interpreted as 'The geese arrive at the water's edge'.
 * 雀入大水為蛤, 'The sparrows enter the ocean and become clams'
 * 菊有黃華, 'Chrysanthemums bloom yellow' – the chrysanthemum is known as one of the few flowers to bloom in autumn.
