I believe that Natsu is a year older than Lucy. The year they came from was 377 to be exact, if you then add the year 777 it's exactly four hundred years so Natsu would have been 11 years old as Lucy was 10. So if Lucy was born 767 that means Natsu was born 366, as to the exact day it's unknown but because his parents named him "Natsu" (summer), as the first day of summer is around the middle of June and not July we could say Natsu's birthday is June 20th 366. http://fairytail.wikia.com/wiki/Lucy_Heartfilia

  • Welcome to Anime & Manga, a Q&A site about anime & manga. This might be a starting point for a good answer, but could you provide some sources/references to back this answer up? Meanwhile, consider taking a quick tour to understand more how this site works.

The Author hasn't provided an official birthday yet. All we know is that he was born some time in the X300 century.


His birthday is July 7th concluding to Hiro Mashima. The year has not been specifically been said yet, but it is some time in when dragons disappeared. Since Natsu was trained by Igneel, he must have been born before this date, presumably several years before to allow time for training and such. So around X777.
