A customer pointed this out so I came here to see how you handle it and it’s the same.
Look at this sample as a reference. https://dhtmlx.com/docs/products/dhtmlxGantt/06_grid_config.html
Develop System is set as a 2-day task starting April 3rd. So that means you will commit April 3rd (day 1) and April 4th (day 2). So why does April 5th get listed as the End date?
What is the logic in this?
Think of it this way. If a coupon has an expiration date of April 5th, that means you can use it on the 4th and 5th but after the 6th. Using your logic, I can use it on the 4th but not on the 5th or later.
Please help me understand this.
