Numbers and dates

Can you remember numbers one to ten?
Here they are again, this time with the form used to express dates.

Latin English Latin English
unus, -a, -um   one primus, -a, -um first
duo, due, duo two secundus second
tres, tria three tertius third
quattuor four quartus fourth
quinque five quintus fifth
sex six sextus sixth
septem seven septimus seventh
octo eight octavus eighth
novem nine nonus ninth
decem  ten decimus tenth
viginti twenty vicesimus twentieth
triginta thirty tricesimus thirtieth
centum one hundred centesimus hundredth
mille one thousand millesimus thousandth

Dates are expressed using ‘first’, ‘second’, ‘third’, rather than ‘one’, ‘two’, ‘three’.
These are always in the ablative case. Generally, the ‘us’ ending becomes an ‘o’.

For example

primo on the first
tricesimo die on the thirtieth day
anno domini millesimo centesimo vicesimo in the year of the Lord one thousand one hundred and twenty (or, 1120 AD)
anno regni regine Elizabethe nono in the ninth year of the reign of Queen Elizabeth
anno regni regis Ricardi filii regis Edwardi septimo in the seventh year of the reign of King Richard son of King Edward

There are more numbers in the reference section on the Dating Latin documents page.
