Writing and reading a year
A year is written in figures followed by он. When you read it, say the whole number; its last element stands before the noun он, so it takes the attributive form:
| Written | Read aloud |
|---|
| 1206 онд | мянга хоёр зуун зургаан онд |
| 1990 онд | мянга есөн зуун ерэн онд |
| 2026 онд | хоёр мянга хорин зургаан онд |
The case ending does the work
The ending on он says how the year is used in the sentence:
| Form | Meaning |
|---|
| 1206 онд | in 1206 |
| 1206 оны | of 1206 |
| 1206 оноос | from 1206 |
| 1990 он хүртэл | until 1990 |
| 1921–1990 онд | from 1921 to 1990 |

Centuries
Centuries are usually written in Roman numerals and read as ordinals: XIII зуун = арван гуравдугаар зуун, XX зуун = хорьдугаар зуун, XXI зуун = хорин нэгдүгээр зуун. "In" a century is XIII зуунд; "of" a century is XX зууны.
To place an event inside a century, add the genitive and a word for the part: зууны эхэн үед (at the beginning of the century), зууны дунд үед (in the middle of the century), зууны сүүлээр (at the end of the century).
XX зууны эхэн үед Монгол тусгаар тогтнолоо зарласан.At the beginning of the 20th century Mongolia declared its independence.
XIII зууны дунд үед Хархорум том хот байжээ.In the middle of the 13th century Kharkhorum was a large city.
Decades: –аад
1990-ээд он is "the 1990s", read мянга есөн зуун ерээд он. It is the same –аад that rounds a number off (гучаад, "about thirty"), placed on the tens: ер → ерээд, гуч → гучаад, so 1930-аад он is "the 1930s".
1990-ээд онд олон зүйл өөрчлөгдсөн.A great deal changed in the 1990s.
