It seems like a subjective question. And scientists HATE subjective questions. I've been oddly fascinated with the subject since 2009, when the U.S. remake of Life on Mars aired it's last episode. (To the many Brits out there that scold us for remaking another proud British tv series, I will remind you that the creators of the original show based it on the "Great American Novel" A Connecticut Yankee in King Arthur's Court by Mark Twain.
But enough of that. The series ending was completely different from the original series. Sam Tyler went to heaven in the original finale, but in the American version the protagonist was simply in a technological induced dream during stasis in order to keep his brain active during the 2 years, 3 months and 22 days journey to Mars. The year is 2035.
Don't we now know we can get to our neighbor in much less time than that? Its presented as what was then science fiction. A lot has changed the past 11 years in regard to Mars travel.

It depends on the specifics (such as whether you want to minimize the travel time or the energy expenditure). Numbers vary from a 9 month one-way trip to a 245 day round trip: https://en.wikipedia.org/wiki/Human_mission_to_Mars#Travel_to_Mars

It would depend on you reference frame. Relative to the traveller or the place of origin.
