Before you start

My google cloud application is not published. You can create your own following https://developers.google.com/calendar/api/quickstart/nodejs and using this code instead

Expected folder structure

credentials/
    credentials.json
    token.json
modules/
    auths.js
    listEvents.js
index.js

Usage

npm run batch 2023-05-09 2023-05-10 to get a single result

npm run daily 2023-05-09 2023-05-10 to get a result per day

On first usage, a browser window will open for you to select account and agree on using this application. This application uses a readonly permission in google calendar.

The results are aggregated on the first keyword in the calendar event. My recommendation is to classify your events per categories (work, fun time, exercise...)

Example

--- 11:00
"[#exercise🏋️‍♂️] Run 10 kilometers"
--- 13:00
"[#IRL👨] lunch with friends"
---17:00
"[#entertainment📺] Watch Netflix"
---18:30
"[#IRL👨] family dinner"
--21:00

Result looks like:

{
    [#exercise🏋️‍♂️]: 2,
    [#IRL👨]: 6.5,
    [#entertainment📺]: 1.5
}
