It can be known that Violet and Sunny were born in 1985 and 1997. The Bad Beginning was made in 1999, when Violet was 14 and Sunny was a baby, two years old. So you can know when they were born. Please don't undo my edit again.
Just because the timeline is not stated in the books does in no way mean that it is set in the publication dates timeline. The story is "timeless" and will remain that way unless Daniel Handler states otherwise.
I did not put those dates there when I joined the wiki. They were placed here before I joined. I replaced them when you took them away because information was being taken from the articles.
I won't undo it, but I'm letting you know what happened.
