Formula & Theory — Cuba Leader Tenure Calculator

The Cuba Leader Tenure Calculator applies the following core formula:

Tenure Days = End Date − Start Date  (in whole days)

Once the total number of days is known, the breakdown is computed as:

Years  = floor(Total Days ÷ 365.25)
Remaining = Total Days − floor(Years × 365.25)
Months = floor(Remaining ÷ 30.44)
Days   = floor(Remaining − Months × 30.44)
