What is correct on 1990 or in 1990?

Answer 1

Oh, dude, it's "in 1990." We're talking about a year here, not a math problem. You wouldn't say "correct on 1990," unless you're trying to confuse everyone. So yeah, it's definitely "in 1990." Like, no big deal, just basic grammar stuff.

Answer 2

The correct preposition to use with the year 1990 is "in." When referring to a specific year, such as 1990, it is more appropriate to use "in" to indicate the time period. For example, you would say "In 1990, I graduated from high school," not "On 1990."

Answer 3

If you are talking about a year, it would be in 1990. If you were talking about what score a person had in a competition, you could say that they were on 1990. So it depends on the context.

In relation to a date specific month then you would refer to the it as "in" - "in march 1990"

to a specific day then you refer to "on" - "on 1st January 1990"
