Use Google location history to figure out where you've been

• go to https://www.google.com/takeout

• click "select none"

• scroll down and click the box next to "Location History JSON format"

• scroll down and select next, then create archive.

Then go to https://github.com/etrombly/country_parser/releases and download the country_parser or country_parser.zip (if you're using windows).

• Unzip your location history

• open country_parser, go to file->import location history, and select your LocationHistory.json

It should output a list of dates and countries visited.
