Standard vs. inclusive counting

The phrase “120 days from today” normally uses standard date arithmetic: today is day 0 and the next calendar date is day 1.

Standard counting Add 120 full calendar days after the start date.
Inclusive counting Count the start date as day 1, so the result is one calendar day earlier.
Which result should you use? Use standard counting unless a contract, policy, court rule or other instruction explicitly says the start date is included.

120 days vs. 4 months

One hundred twenty days is a fixed duration. Four months is calendar arithmetic, so the two results can differ because calendar months contain different numbers of days.
