A few notes:
1) The number of shared dates between state contests was relatively few in 1976.
2) Relatedly, the closest thing to a Super Tuesday in 1976 was May 25. Six states held primaries on that date. Outside of that, there were several dates with three contests, but that was the most.
3) Barely half of the contests were primaries (28 if you count the Montana primary.). The remaining states held caucuses, and of those caucus states, only 5 held both their Democratic and Republican contests on the same date. That leaves 17 states with separate dates for their major party caucuses. That number climbs to 18 if you count the Montana primary/convention split between the Democrats and Republicans, respectively.
