Currently the Australian Open starts in the third week of January, but Nadal thinks players would benefit if it started in February.
Nadal has been a vocal critic of the packed professional tennis schedule in the past, and it appears the 14 time Grand Slam winner still thinks the schedule is hard on players.
Nadal said: "For us, it is important to spend the new year at home. It important to spend Christmas at home with family. Those dates are very important. Players have family, players have small kids. You want to spend that time with them.
"With this calendar, it is tough to have and enjoy this period of time with your family. It is true that if we went two weeks [later], it would be better.
"Two tournaments would be the right period of time before the tournament to play. Today we are talking for talking, because I don't see a change in that calendar for the future."
The world number three booked his place in the last 16 of the Australian Open with a 6-1 6-0 7-5 victory over Israel's Dudi Sela on Friday.
