Час is a masculine noun; the ending pattern above repeats across most masculine nouns, so every table you learn makes the next one cheaper.

Look up any other word in the Russian declension tool, see where час ranks in the most common Russian words, or start from Russian cases explained if the table above is new territory. More vocabulary lives in Russian words by topic and Russian phrases.

12 forms is a table. Using them is a skill.
