Month should be considered qualitative nominal data. With years, saying an event took place before or after a given year has meaning on its own. There is no doubt that a clear order is followed in which given two years you can say with certainty, which year precedes which.
Are dates nominal ordinal interval or ratio?
Often, you will treat dates as ordinal, e.g. if you are looking at something and want to model it in terms of who was president at the time. The general case would be to treat them as interval, since the starting point is arbitrary but the units are fixed (so, 12–25 is not double 6–12).

Is birth order an ordinal variable?

How do you find the ordinal date?
The most trivial method of calculating the ordinal date involves counting up all days that have elapsed per the definition:
- Let O be 0.
- From i = 1 .. m – 1, add the length of month i to O, taking care of leap year according to the calendar used.
- Add d to O.

When are dates nominal, ordinal, interval or ratio?
Are dates nominal, ordinal, interval or ratio? Dates themselves are interval, but I could see cases where they could be any of those four. If you are not positing any monotonic change over time, and you have only a few dates, then nominal might make sense.
