Relationship between the start date, end date and duration:

It is important to explain the relationship of start date, end date and duration; so you can understand how the application performs the calculations. The existing relationship is:

End Date = Start Date + Duration

In this way, for example, if an activity has a start date = 01/15/2021 00:00 and has a duration of 1 day. The end date would be = 01/16/2021 00:00.

When we work with hours, we can select the exact date and time each activity starts. For the other time units, when selecting the date, 00:00 hours will be taken as the start time.

Example:

Make a Gantt chart with the following data:

Activity Description Start Date Duration (days) Advance Immediate precedents
A Define kickoff meeting 09/02/2020 1 100%
B Define objectives 09/03/2020 4 100% A
C Determine the requirements 09/07/2020 5 100% A
D Hardware requirements 09/09/2020 2 80% C
E Final resource plan 09/11/2020 4 50% A,B,C
F Personal 09/16/2020 1 50% E
G Technical requirements 09/17/2020 4 0% E
H Database development 09/22/2020 2 0% G
I API development 09/23/2020 4 0% G
J Client User Interface 09/25/2020 4 0% G
K Testing 09/24/2020 8 0% H,I,J
L Proof 10/02/2020 3 0% K
M Hardware Configuration 10/05/2020 2 0% L
N System test 10/07/2020 3 0% M
