We have made a little tool that some people may find useful for planning your time. This tool will show you the number of work hours left in the day, week, month and year so that you can see how much time you have left to be productive. It is customizable for your work schedule. Do you know how many hours you have left to work this year?
If you give time estimates to tasks, you can use this tool to help you schedule tasks effectively and not make the mistake of over-scheduling yourself. For example, there are only 166 work hours left in October (at the time of this post, assuming 8 hours worked per weekday and standard US holidays). Given this, it would be foolish and ultimately discouraging to schedule 200hrs of work for this month.
I have personally been using this tool for about a month to plan my weeks, and it has been a big help with prioritization.
