Row 20 of 18–45
Chinese Gender Chart: Lunar Age 20
At lunar age 20 the traditional chart predicts a boy in 9 of the 12 lunar months and a girl in 3. Here is the full row, what makes it different from the rows either side of it, and how to tell whether 20 is actually your lunar age.
What row 20 says
If the mother’s lunar age at conception is 20, the traditional chart predicts:
- Boy in lunar months 2, 4, 5, 6, 7, 8, 9, 11 and 12
- Girl in lunar months 1, 3 and 10
So this row leans boy, at 9 months out of twelve. Across the whole chart the average row gives 5.9 boy months, and the extremes are row 18 with 10 boy months and row 21 with 1.
The longest unbroken stretch in this row is 6 consecutive months of boy, running from lunar month 4 to 9.
One thing worth repeating, because it is where most people go wrong: these are lunar months. Lunar month 1 begins on Chinese New Year, which falls between 21 January and 20 February, so it never lines up with January. The table further down converts them into real 2026 dates.
How row 20 differs from its neighbours
Rows next to each other on this chart are not gentle variations of one another. Being off by a single year of lunar age changes the answer in a large share of months, which is exactly why the Chinese New Year cutoff matters so much:
- Against lunar age 19, the prediction flips in 8 of 12 months: lunar months 1, 2, 3, 4, 5, 10, 11 and 12.
- Against lunar age 21, it flips in 10 of 12 months: lunar months 1, 2, 4, 5, 6, 7, 8, 9, 11 and 12.
If a calculator works out your lunar age with a simple “add one to your age” rule instead of checking Chinese New Year, it can land you on the wrong row entirely, and as the numbers above show, a wrong row is not a near miss.
Are you lunar age 20?
Lunar age is not your ordinary age. You count as one year old on the day you are born, and everyone gains a year together on Chinese New Year rather than on their own birthday. So lunar age 20 does not map onto a single Gregorian birth year; it maps onto a lunar year that starts and ends on Chinese New Year.
| Lunar age 20 during | Born between | Lunar year | Zodiac |
|---|---|---|---|
| 2026 | 18 Feb 2007 – 6 Feb 2008 | 2007 | Pig |
| 2027 | 7 Feb 2008 – 25 Jan 2009 | 2008 | Rat |
| 2028 | 26 Jan 2009 – 13 Feb 2010 | 2009 | Ox |
| 2029 | 14 Feb 2010 – 2 Feb 2011 | 2010 | Tiger |
Notice that each window starts on a Chinese New Year, not on 1 January. Someone born in mid-January 2008 still belongs to lunar year 2007, because Chinese New Year had not arrived yet. That single detail is the most common cause of a wrong result.
