Magellan’s voyage- Miscalculated Day??
Magellan’s voyage, starting in 1519, sailed West from Sanlucar de Barrameda, Spain to the Spice Islands by Indonesia, then back to Sanlucar de Barrameda. Their journey ended in 1522. According to the voyage’s ship logs, the date was Saturday 6, Sept. 1522. The Spainiards on land said the date was Sunday 7, Sept. How could this happen? I know it had something to do with the voyage sailing against Earth’s rotation, something to do with the sun setting.. I just dont have an exact answer. This is before the International Dateline, mind you. Remember that they are going WEST! The sun rises in the EAST and sets in the WEST. Help! Please give me a detailed answer that i could work into an essay.

Well, the international dateline didn’t technically exist, but it did in reality.
It doesn’t matter which direction you travel, if you go around the world, you will be off by one day. If you travel West you lose a day, and East you gain a day.
So, Magellan travelling west, lost a day, and arrived on 9/7 believing it to be 9/6.

It is the question of slow-boat to China syndrome
During My recent trip to Spain I had the same discussion with a Spaniard and his reasoning was that in those days ship needed winds for sailing and the speed at which we travel today gives us the impression that the dateline had an effect.

If you follow wildeyedredhead’s logic, you could theoretically go really far south, close to Antarctica, where the lines of latitude are very close together and if you traveled west in a fast boat, every time you went all the way around, crossing all 24 lines of latitude, you would gain a day. Going east, you would lose a day. Do it fast enough and you’ve discovered time travel.

The international dateline was not taken into effect. They had no concept thereof in his day, and accurate computation of Longitude itself was a concept that required an accurate marine chronometer. That did not occur until Harrison completed his chronometer in the late 1700’s. (see link)
