Variation in da between Moz and ahrefs

Hiya bit of a noobie question.
I have used the search function but can't find an answer.

What causes such a difference between DA scores on moz and ahrefs? For example on moz my site has a DA score of 25 with a zero spam score for backlinks but in ahrefs my DA score is 7. Just wondering what one is more accurate and why there would be such a difference. Personally I think the DA score probably is 7 as the sites only around a month old but the difference has got me scratching my head lol
