Activity Manager allows registering and reporting of time, travelled distance and expense activities in Microsoft Excel. The activity registration is done by week on a form that looks like the page in an agenda. At startup the Activity Manager main dialog creates a simple and easy to use Excel workbook of the desired year. A week selector on the form allows browsing the year by week like turning the pages of your agenda. A dropdown box in the form allows easy selection of your activities in the week. Totals of the various activity types are calculated and presented to you while entering the data.
