Each service starts on a different date because the services depend on each other. Starting with Phase $2,$ enter a formula without using a function that adds $4$ days to $t$ G$-131$ service date. Next, use a similar formula that subtracts $3$ days from the G$-13$: service date. For the next date, use a similar formula that adds $2$ days to the $F-125$ service date. Finally, use a similar formula that adds $2$ days to the G$-131$ service dat Copy the formulas in Phase $2$ down to fill the rest of the schedule.

Next to the cell labeled "Start date", use a function to find the earliest of the project schedule dates.

In the appropriate cell, use a function to find the latest of the project schedule dates
