2024 is the current year and it's the same as the number of lines of code. I don't think describing it as ironic is correct though.

The other response is correct that this is not ironic. Roughly speaking, irony is when something happens that is the opposite of what you'd expect. A firefighter's home burning down is ironic. Sometimes irony is related to unfortunate or funny coincidences/timing, and it's easy to confuse the two. Alanis's song Ironic famously has a lot of examples of this. Rain on your wedding day--is that ironic? Maybe? You certainly hope there is no rain on your wedding day, but I don't think there's an expectation that there won't be rain. Now if your parents decided to get a divorce on your wedding day, I think that's ironic.

But the parent commenter dilutes the definition further. A project with 2024 lines of code in 2024 is just an amusing coincidence. There's no reason why you'd expect a project in 2024 to not have 2024 lines of code.
