Relationship between the start date, end date, and duration:
It is important to explain the relationship of the start date, end date, and duration to 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. 00:00 hours will be taken as the start time when choosing the date for the other time units.
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 |
