Pesachim 53 - יו"ט שני - How Social Context can Define us

The Daf seems to deal with Shemita. However there is an overarching theme about the relationship between people and things, and the geographical, time and ciltural context in which they are. The Gemarra explores the impact of this context on Shemitta produce as it is moved from one zone to another. Similarly we explore the impact of zones on the law requiring us to keep 2 days yomtov outside of Israel.
