While there are more holidays celebrated by Jewish communities, my work here is focused on Shalosh Regalim. Shalosh Regalim is composed of three required festivals; Passover, Pentecost, and Tabernacles/Booths. 

I see these three festivals fitting into two arcs. The “Salvation Arc” moves from physical salvation, as seen in Passover to spiritual salvation, as seen in Pentecost. The second arc is the “Living in Joy Under God Arc” as seen in Sukkot, Booths.”
