This is a poll, please answer in the comment section.

Picture a spreadsheet that's intended to be a timesheet for an employee. On one axis, you have the days of the month. On the other axis, you have the various tasks you did that day. For each task, you enter the amount of time you spent on it that day. Every row and every column totals itself at the end, so you can quickly see how much time was spent on each task in a month, and how many hours were worked in a day.

Do the days go down the side and the tasks across the top, or vice versa?
