If it was opened on a PC at the entrance of a company, for example, the employees could use it for recording the entrance and exit time. The spreadsheet allows to record the working hours of more than one person.
At the end of each week I get a summary of how many hours I have worked on my project. If I forget to record the moment when I started/stopped working, I can do it afterwards by clicking on the “Insert single entry manually” button (if I forget to enter both the start and end time I click on “Insert double entry manually”). I repeat the operation when I stop working on my project. The Time card calculator spreadsheet automatically records the current time and date. Once the spreadsheet is open, I select my name and click on the “Enter/exit” button. I thought this operation was a waste of time, so I decided to create the Time card calculator, a spreadsheet that could do this operation for me. Every week I then calculated how many hours I had worked. I started to note down the hours of the day when I started and stopped working on the project. Knowing how much I like taking photographs, I decided to set up some boundaries on the number of hours that I was allowed to spend on the project every week.
I started to work on this spreadsheet after I decided to start a photography project.
