can type $"1"$ and press Enter to fill each cell. Also, add the Start and Finish dates to the yellow cells on the bar chart. Please note that all tasks except $C$ and $H$ are based on $5-$day calendar $($MTWRF as working days$),$ therefore, they can not begin or finish on the weekend. Tasks $C$ and $H$ are based on $7-$day calendar and therefore their bars can continue over the weekends. An example is given for Task A$.$

Next, calculate the ES $($Early Start$)$ and EF $($Early Finish$)$ for the network diagram below the bar chart by conducting the forward path calculations. Please note that the work days $($not the calendar days$)$ shall be used for your calculations. The ES for A and $B$ are given as an example.

Once you reach to the Finish task, perform the backward path calculations and find the LF $($Late Finish$)$ and LS $($Late Start$)$ dates. You only need to fill the yellow cells on the network diagram.
