9.1 – Ordinal Numbers (1st – 31st)

We learned ordinal numbers in 7.2 – Ordinal Numbers (1st-12th) in order to use conversational clock time. Now we’re going to need them again to tell dates.

The table below lists ordinal numbers (first, second, third, etc. — i.e. the numbers used to tell what order something comes in). These ordinal numbers are important now because we are going to learn how to state the date. Therefore, the table below gives 1st – 31st.

As you can see from this table, many of the ordinal numbers look very much like their cardinal counterparts. You really can just memorize them, however here are a few things that might help you:

  • For many of them, all you have to do is add -ý.
  • For the numbers pět, devět, deset, dvacet, třicet, you just have to change -et/ět → –átý, pět → pátý, dvacet → dvacátý, etc.
  • Note that with numbers such as 21st, 22nd, etc., both numbers in Czech are ordinal, i.e. dvacátý první. Alternate forms also exist where the numbers are reversed (jednadvacátý, dvaadvacátý, etc.)
  • Ordinal numbers are adjectives and thus take normal adjectives endings. Just by looking at these, you can tell that most of them are hard stem adjectives (end in -ý), while první and třetí are soft stem.

In Czech, these are either written out in full (první, druhý, etc.) or they are marked by putting a period after the number, so 1. den = první den, 2. den = druhý den, etc.
