Sorry to revive this this old threat, but this is wrong. Reinhard's age was listed as 19 both in the WN author notes and the zeropedia. For reference, Rem & Ram's ages were listed as 17 in both versions so that should give you an idea about the time frame in reference.

Further, the statement "I will be nineteen this year" cannot be true in regards to Reinhard because it implies his 19th birthday is later that year, but his birthday is January 1st, the very first day of the year. The only way in which it can be even remotely true is if he turns 19 in few hours or so.

Basically Reinhard is 19 for the first 4 arcs and 20 onwards.

Edit: There is also this from Rom's 2018 birthday Q&A confirming that Reinhard is 20:

Q: What does Old Man Rom think of Master Swordsman Reinhard?

A: While thinking of him as dangerous, he also thinks that 'he's still just a twenty-year-old kid'.
