Cold Dew (寒露, Hanlu): Dates, Meaning and Autumn Habits

Cold Dew (寒露, Hanlu) is the 17th of the 24 solar terms. It begins when the sun reaches 195 degrees of ecliptic longitude, and in the Four Pillars calendar it opens the Dog month (戌).

When Cold Dew begins

In 2026 the sun crosses 195 degrees on 8 October at 15:29 Korea time. In 2027 the same moment falls on 8 October at 21:17, about 5 hours 48 minutes later on the clock. That drift of roughly a quarter day each year is why a term's hour changes from year to year, and why a leap day every fourth year pulls it back again.

Cold Dew is a jie (節) term, one of the twelve that start a new solar month. From it, the tradition counts the 戌 month, which in 2026 carries the pillar 戊戌 and in 2027 the pillar 庚戌. The next term, Frost Descent, follows 15 days 3 hours 9 minutes later in 2026.

What the name means

寒 means cold and 露 means dew. Two terms earlier, White Dew (白露) described dew that simply shows up white on the grass. By Cold Dew the dew feels chilly to the touch in the early morning. The calendar watches one thing, dew, and records how it changes over a month.

What changes in nature

In Korea this is the heart of clear autumn weather. Skies are high and dry, nights get cool quickly, and the gap between morning and afternoon temperature is wide. Mountain maples begin turning from the north and from the peaks downward, and in the fields the rice harvest is being finished and threshed.

The classical Chinese almanac lists three five-day signs for this term: wild geese arriving as guests, small birds entering the water to become clams, and chrysanthemums showing yellow flowers. The middle one is poetic folklore rather than biology, but it shows how people once read the season through birds and flowers.

Seasonal foods

Chrysanthemums tie Cold Dew to the Double Ninth festival (重陽, the ninth day of the ninth lunar month), which usually falls close by. In Korea people made hwajeon, small pan-fried rice cakes decorated with chrysanthemum petals, and enjoyed the flowers outdoors. Freshly harvested rice, chestnuts and jujubes also reach the table now; a bowl of chestnut rice is a natural fit for the week.

Gentle habits for the season

Add a thin layer in the morning and evening, and take it off at midday rather than dressing for the warm afternoon.
Keep feet warm after sunset; cool dewy air is felt first at the ankles.
Dry air arrives with clear weather, so sip warm water or tea through the day and use lotion on hands.
Enjoy the long, bright afternoons for a walk while the light is still generous.

A line of poetry

Bai Juyi's short poem 《暮江吟》 (Evening Song by the River) ends with a ninth-month night: 「可憐九月初三夜，露似真珠月似弓。」 "How lovely, the night of the third of the ninth month: dew like pearls, the moon like a bow." The ninth lunar month is exactly the stretch that Cold Dew opens, and the poem catches the same cold, bright dew.

Questions

Is Cold Dew the same date every year?

Nearly. It is tied to the sun reaching 195 degrees, so it lands on 8 or 9 October in most years; the clock time moves by about 5 hours 48 minutes from one year to the next, as 2026 and 2027 show.

Why does the month change at Cold Dew and not on 1 October?

The Four Pillars calendar uses solar months that begin at the twelve jie terms. Cold Dew is the jie that begins the 戌 month, so a birth one minute before 15:29 on 8 October 2026 still belongs to the 酉 month.

What is the month pillar after Cold Dew in 2026?

戊戌. The year 丙午 has the stem 丙, and the five-tigers rule for 丙 or 辛 years gives 戊戌 for the ninth solar month.

Which term comes next?

Frost Descent (霜降), at 18:38 KST on 23 October 2026.
