Chinese, Japanese, and Korean all appear to use the Sino character “月” (yuè) as their root word for the term ‘month’ as in months of the year. This character is originally a pictographic representation of a moon and is related in meaning to the moon or lunar cycle. Unlike many western calendars and time-tracking systems, Asia often based their time-keeping on the cycle of a moon as it changed through its phases. Consequently, one month for them would be the completion of one lunar cycle (which is around 29 days).
Although rooted in the same concept and character, each of the three languages pronounces the term differently and Korea uses Hangul which is a phonetic writing system rather than the ancient pictographs Kanji and Chinese are grounded in.
MONTH
Chinese
月
Yuè
(Yoo ə)
Moon
Originally ‘crescent shaped’ but shifted / added lines to avoid looking like other characters (口 ,日 )

Japanese
月
Gatsu
(gaht- s – short u)
Moon
Kanji uses the Sino character, but pronounced differently.

がつ
Gatsu
(gaht- s – short u)
Moon
Hiragana letters, still the same pronunciation as Kanji

月 is usually pronounced as がつ (Gatsu) when combined with other characters in a word. When standing alone, it is usually pronounced as げつ (Getsu)
Korean
월
Wol
Moon
Pronunciation is the older Korean reading of 月

All three languages appear to generally create the name of each month by combining the number with the term for month:
Number + Month
CHINESE
Emphasis in pronunciation is on the number, not the “yuè“
| Chinese | Romanized | English |
|---|---|---|
| 一月 | yī yuè | January |
| 二月 | èr yuè | February |
| 三月 | sān yuè | March |
| 四月 | sì yuè | April |
| 五月 | wǔ yuè | May |
| 六月 | liù yuè | June |
| 七月 | qī yuè | July |
| 八月 | bā yuè | August |
| 九月 | jiǔ yuè | September |
| 十月 | shí yuè | October |
| 十一月 | shí yī yuè (10 + 1) | November |
| 十二月 | shí èr yuè (10 + 2) | December |
JAPANESE
Both Kanji and Hiragana use the template “Number + Month” and the pronunciation is the same. They just use different characters (月 for Kanji / がつ for Hiragana . . . both pronounced “gat-su”).
Emphasis in pronunciation is on the number, not the “gat-su”
It is helpful to note some of the Chinese pronunciation is similar in some of the numbers (e.g., the ‘chi’ in seven and ‘san’ is just the same in both languages).

|---|---|---|---|
| 一月 | いちがつ | ichigatsu | January |

| 十二月 | じゅうにがつ | juunigatsu (10 + 2) | December |
KOREAN
Korea has two separate numbering systems, but uses the “Sino-Korean” in their months. Consequently, there is often a similar pronunciation between the Korean-Chinese or Korean-Japanese numbers here. For example, ‘go’ and ‘o’ for 5 and ‘san’ and ‘sam’ for 3.
