DATE : stocke une date au format AAAA-MM-JJ (Année-Mois-Jour) ;

TIME : stocke un moment au format HH:MM:SS (Heures:Minutes:Secondes) ;

DATETIME : stocke la combinaison d'une date et d'un moment de la journée au format AAAA-MM-JJ HH:MM:SS. Ce type de champ est donc plus précis ;

TIMESTAMP : stocke le nombre de secondes passées depuis le 1er janvier 1970 à 00 h 00 min 00 s ;

YEAR : stocke une année, soit au format AA, soit au format AAAA.
