What is an Early Start Date (ES)?

The phenomenon of Early Start (ES) is similar to setting an alarm clock for the earliest time you may begin a work within your project timeline. It is the earliest moment at which a certain action may begin without waiting for any other activities to be completed. Consider it the point at which you can begin working on anything as soon as you’re ready, without having to wait for anything else to happen. It aids in project planning by indicating the earliest feasible beginning point for each activity, giving you a clear indication of when things may start.
