- Timetrack is a simple commandline program for analysing your own Mac calendar data.
- The idea for this project was inspired by Devi Parikh's calendar-based time management technique (I highly recommend reading her blog post: https://blog.usejournal.com/calendar-in-stead-of-to-do-lists-9ada86a512dd).
- After experimenting with Devi's method for a while, I made some adaptations and developed Timetrack as part of my time management and productivity workflow.
- If you are only interested in how to install and use Timetrack, feel free to skip to Setup.
In her excellent blog post, Devi Parikh proposed to use a calender-based approach for time management instead of commonly used to-do lists (https://blog.usejournal.com/calendar-in-stead-of-to-do-lists-9ada86a512dd). The key idea is to schedule every task in your calendar (like you would do with a meeting) instead of keeping it on an ever-growing to-do list. This has the advantage of making the required time visible and making you think about how to best allocate it to certain tasks. I tried Devi's calendar-based time management system and really liked it. Its simple and effective. It requires you to break down large problems into more manageable chunks and encourages focusing on a single well-defined task at hand without getting distracted.
After trying this system for a couple of weeks, I made the following adjustments:
- Keep separate calendars (and don’t move tasks to the ‘done’ calendar)
- Record your productivity levels
- Review what is/isn’t working
- Analyse your calendar and productivity data with Timetrack
In her blog post, Devi recommends using three calendars: ‘meetings’, ‘to-do’ and ‘done’ (there is also the ‘block’ calendar to reserve time for eating/sleeping/etc.). The idea is simple: place all new tasks in the ‘to-do’ calendar and then move them to the ‘done’ calendar once you’re finished. However, this doesn’t take into account that tasks differ in importance and difficulty.
I therefore keep separate calendars for major vs. minor work-related tasks. Major tasks are tasks which will get you closer to your current professional goal. For example, if your main goal is to successfully complete your PhD, this could include tasks such as writing a paper, analysing data or writing code. Major tasks naturally tend to be relatively difficult and require high energy and focus. In contrast, minor tasks do not immediately contribute to your main goal, but still need to get done. These could include writing emails, planning your schedule for next week or reading a reading group paper unrelated to your own research. In contrast to major tasks, minor tasks tend to require lower energy levels. By placing major and minor tasks in different calendars, one look on your weekly schedule makes it immediately clear how important your tasks are and how long they will probably take. This is useful information when it comes to optimally scheduling your tasks. For example, if you are more productive in the morning, this prime time should be reserved for working on your major tasks, while minor tasks can be deferred to after lunch when concentration levels and productivity tend to be lower. Although the feeling of moving a task from the ‘to-do’ to ‘done’ calendar can be rewarding, this action deletes valuable information regarding the task’s importance when analysing past calendar data (see point 3). Therefore, each task should be kept in its respective calendar after it’s done (see point 2 for what you should do instead after finishing a task). Tasks which are not work-related (e.g. working on a side project, eating, sleeping) go in the ‘life’ calendar, so they can be easily omitted during calendar analysis. You can also create additional calendars based on your personal needs (e.g. for travel or health/wellbeing).
(Calendars: blue=major, yellow=minor, light green=life, dark green=health, grey=travel)
If you follow the instructions above for a couple of days, your calendar will soon contain a lot of interesting data, including how much time you spent on what kind of tasks and when. However, it doesn’t provide any insight into your productivity levels while working on different tasks. After completing a task, assign a score between 1 -unproductive- and 5 -highly productive/flow state like- to the accomplished task (You can store the productivity score in the ‘location’ section of the calendar entry which is not ideal, but has the benefit of making it show up in the weekly calendar view). Over time, rating your own productivity will help you to get to know your own working rhythm. It might also help to think about questions such as: Are you most productive in the morning or evening? What would be the best task to match your current energy level? Do you need a short walk after a stressful meeting to recover your energy level? Use this insight into your productivity patterns when scheduling your tasks.
At the end of the week, schedule a short weekly review task for Friday afternoon. The idea is to have a look at your calendar at the end of the week and think about the following questions: What went well? What didn’t? What could I improve next week?. Write down the answer to these questions in your calendar to keep yourself accountable and learn from your experience.
By following this technique, your calendar will accumulate a large amount of valuable information over time. Initially, you can simply look at your weekly calendar view to observe your working patterns, but as time progresses it becomes difficult to identify trends. That's why I wrote Timetrack. Timetrack is a simple tool for analysing your calendar data. Its commandline interface allows you to adjust several settings, including which time periods and calendars to analyse (e.g. only major, minor and meetings). In the basic setting, the program reads your calendar data and summarises how much time you spent on which kind of task over a certain period of time to help you track your own progress.
timetrack_multi_cal -calendars Major.ics,Minor.ics,Meeting.ics -start 2019-11-04 -end 2019-11-18 --all_days
However, without taking productivity into account, the summary is only quantitative and may encourage you to maximise working hours rather than productivity. Therefore, you can use Timetrack's --prod_score
flag to visualise your average daily productivity alongside quantitative information, allowing you to focus on increasing your productivity rather than working time.
timetrack_multi_cal -calendars Major.ics,Minor.ics,Meeting.ics -start 2019-11-04 -end 2019-11-18 --prod_score --all_days
pip install -r requirements.txt
- Edit timetrack.sh in an editor, so that TIMETRACKDIR points to the location of your timetrack folder
export TIMETRACKDIR=/path/to/timetrack # e.g. Users/nicole/code/timetrack
- Run timetrack.sh for easy commandline access to
multi_cal
andsingle_cal
source timetrack.sh
- To use on Windows, change '%TIMETRACKDIR' to the location of your timetrack folder in both
timetrack_multi_cal.bat
andtimetrack_single_cal.bat
. - Add the timetrack folder to the system path environment variables. This allows the use of
timetrack_multi_cal
andtimetrack_single_cal
from anywhere in the command line. On Windows 10, this is done viaControl Panel > System and Security > System > Advanced System Settings > Environment Variables
. Then double click onPath
in System Variables then theBrowse...
button.
All other setup and usage will be the same as above. How you export the .ics files depends on your calendar client.
- Now you can directly call
timetrack_multi_cal
ortimetrack_single_cal
from the commandline. As the name suggest,timetrack_single_cal
analyses data from a single calendar, whiletimetrack_multi_cal
provides a summary for multiple calendars. Calendars and time interval are adjustable through commandline arguments:
timetrack_multi_cal -calendars Major.ics,Minor.ics,Meeting.ics -start 2019-11-04 -end 2019-11-16 --prod_score
==>spent 2 days 19 hours 32 minutes on tasks from 2019-11-04 to 2019-11-16
- Major.ics tasks: 2 days 1 hours 15 minutes (avg. productivity: 4.1)
- Minor.ics tasks: 0 days 10 hours 21 minutes (avg. productivity: 3.0)
- Meeting.ics tasks: 0 days 7 hours 56 minutes (avg. productivity: 3.4)
