The day before yesterday (December 30) he was 25.
He turned 26 on December 31.
He talked about it on January 1. That year he would turn 27, so "next year" he would turn 28.

Well, if you were 25 two days ago, I am assuming your birthday was yesterday, and assuming yesterday was New Years Eve, that means you were 26 yesterday, you are going to be 27 this year and 28 next year.

that only works if when you say "the next year" being the 31st. If you say it meaning Jan 1st, which is the day he is on, then he would still be 27.

Febuary 29, xxxx

the riddle mentions that it's a day in a year, it doesn't say that it's a day in EVERY year.
