How old was L in the Death Note series? In the Death Note series, it is seen that while L and Soichiro Yagami are observing Light through the cameras, L says that he used to do a lot of pointless things at the age of seventeen.


  


Later, we see that he is giving the same exam as Light, who is seventeen years old at that time.


  


This made me curious. What exactly is L's age?
As stated in the wikia, L's age is 24-25 years old.

Also, in Death Note 13: How to Read, it is stated that L was born on October 31, 1979 and died on November 5, 2004. From this we can calculate that L was 25 years old at the time of his death.
