I can't find a specific link, but numerous times it was mentioned the dragons disappeared seven years ago.

7 =/= 20

Huh? I'm pretty sure they said it was in year 777 and that was on her tombstone as well... Then again I've started with the anime and continued with the manga so that might have influenced it...

Edit: http://fairytail.wikia.com/wiki/Lucy_Heartfilia

'In her home, Lucy kept a good relation with the staff in the estate and presumably her mother until she passed away when Lucy was around the age of ten[5] on July 07, X777; the same day that the dragons looking after Natsu, Wendy and Gajeel Redfox disappeared. However, her father was overly obsessed with his business and money, often neglecting his daughter, resulting her to run away from home just over a year before the beginning of the story.[6]'

I found it. In that fragment, Caprico was referring to the day he made the promise to protect her family not the day she died.
