unlike Christmas,why is it that Easter have no fixed date? who determines Easter dates? If we believe that Christ was crucified on friday, why do we have debate over which day is the Sabbath?

Easter falls on the first Sunday after the Full Moon date, based on mathematical calculations, that falls on or after March 21. If the Full Moon is on a Sunday, Easter is celebrated on the following Sunday.
Although Easter is liturgically related to the beginning of spring in the Northern Hemisphere (March equinox) and the Full Moon, its date is not based on the actual astronomical date of either event.
March 21 is the church's date of the March equinox, regardless of the time zone, while the actual date of the equinox varies between March 19 and March 22, and the date depends on the time zone.
The date of the Paschal Full Moon, used to determine the date of Easter, is based on mathematical approximations following a 19-year cycle called the Metonic cycle.
Both dates may coincide with the dates of the astronomical events, but in some years, they don't.

why is christmas fixed?

Christmas is fixed because it a day set aside aside by many Christians to celebrate Yeshua's birth although there are issues with that date

The Jewish calendar I suppose because the calendar is what they use mostly now.

wow jewish calendar,
Cool, i read somewhere in Exo 20:8 about keeping the sabbath, but today the debate is on,that sunday is the sabbath, does this not contradict Easter,since it was clear tha christ rose up first sunday of the weeek(sunday) meaning saturday is the actual sabbath?

Jesus was resurrected the Sunday after Passover, so Easter's date is set to that date, the Sunday after Passover. This is achieved by setting Easter as the first Sunday after the first full moon after the start of Spring.

Now you might ask, why does Easter sometimes not fall on the Sunday after Passover? In 2016, for example, Passover was April 23 while Easter was March 27. That's a more complicated matter; the quick explanation is that the date Passover is celebrated by Jews some years is actually incorrect.

Here's the less quick, but still simplified, explanation. Passover is to start on the 15th day of the Hebrew month of Nisan. Now, each month of the Hebrew Calendar is 29-30 days, in order to have each of their months start with a new moon, change to a full moon midway through (putting Passover, halfway through Nisan, under a full moon), and then return to a new moon for the start of the next month. The problem is that the 12 months of this that make up the Hebrew year adds up to 354-356 days rather than the full 365 days there are in a solar year (a solar year being the amount of time it takes the Earth to orbit the sun), so every so often they add in a 13th month to the Hebrew calendar to balance it out. This is especially important for Passover, as it's to be celebrated in the Spring, so the extra month was also used to make sure that Passover wouldn't fall before the start of Spring.

So, Easter is the first Sunday after the start of Passover. And as Passover is, as noted above, the first full moon that happens after the start of Spring, therefore Easter ends up being the first Sunday after the first full moon after the start of Spring in order to keep with that timing.

So returning to the question advanced a few paragraphs ago, why does Easter's date sometimes differ considerably from the date of Passover? It's because the current mechanisms that are used to calculate the years in which the Jewish Calendar adds the extra month (which were put in place in the 12th century, I believe) aren't perfectly accurate. Every year on average it drifts about 6 minutes out of sync with the solar year's length. That doesn't seem like much, but it adds up over the centuries. As a result, some years incorrectly push forward Passover an extra month. There's been some discussions as to how to fix up the Hebrew Calendar calculations to stop this, which would also align it with Easter every year, but the proposals haven't been enacted yet.
