Genèse 7:11,13,14
L'an six cent de la vie de Noé, le second mois, le dix-septième jour du mois, en ce jour-là toutes les sources du grand abîme jaillirent, et les écluses des cieux s'ouvrirent.…

From this, it appears, that Noah was in the ark a complete solar year, or

365 days; for he entered it on the

17th day of the

2nd month, in the

600th year of his life, and continued in it till the

27th day of the

2nd month, in the

601st year of his life, as we see above.
