I wrote something more automatic for myself. I ask the Google Calendar API how many hours I spend in meetings that week. From that I calculate how many working hours I have for other things. I then use the WakaTime API to get how many hours I spent working already (making sure to not double count during meetings). WakaTime can track my editor usage, terminal usage and work in Chrome (e.g. PR reviews). I use a separate Chrome profile to make sure I only track work-related browsing time, and Choosy to open links to our company GitHub automatically in the work profile. I show a summary of the time spent and left in my terminal prompt. Overall really happy with it!
