This is an Excel Gantt chart template that allows you to manage your tasks by the hour.
Although the cells are divided into hourly units, a dotted line is displayed in the middle, so you can make a schedule in 30-minute units.
By default, the time is allocated from 7:00 to 23:00, but you can also set your own "start time" so that the table is automatically set to the hourly time.
You can add columns to the table by adding "task", "start time" and "end time".
Adding a new column does not affect the automatic calculation of time.
