if you make a schedule in excel, you need columns and rows, so that in order to write in the rows the days of the week and in each box things that have to be done and in the columns put the hours to have a better orientation in the schedule, the label serves to indicate the activity at a certain time, so I think that what is not needed so much is the header, since we all know that it symbolizes a day of the week, unless it was a calendar there if the heading to be able to indicate the month in which it is.
