Garmin connect app shows incorrect 12 month running milage

Observation: only 11 months shown from current date.

Expectation: is 12 months to be shown. Would also be nice to have year to date distance.

My Garmin Connect Mobile app shows 12 months. Now we are in December 2020, and the stats show 12 months from Januray 2020 to December 2020, exactly as expected.

If you want it more accurate than that (not 12 months, but 365 days), then use the Garmin Connect Web » Progress Summary Report instead. It allows you all of that, and more. In the first dropdown box, select "Progress Summary", in the second one "Custom Dates" and then the starting and ending dates, and in the third dropdownbox, select "Running"

I guess it is a matter of definition and presentation. You would like to see 1 year back from today. Garmin shows the current month (which is 1 month) and 11 months back which totals to 12 months/1 year.
It is the same if you choose to view 7 days. It will show today and 6 days back which is a total of 7 days. 

To show a part of the first month/week/day in a graph would be strange since the value will change depedending on at what time you look at it.

Just as trux says you should use the more advanced reports and in Progress summary you can get more exact values.

To see the year to date distance there are two ways that I know of:

1. View the calendar: https://connect.garmin.com/modern/calendar Switch to year, scroll down and select the activity type you would like to get the year total for.

2. Use the Progress summary report: https://connect.garmin.com/modern/progress-summary Group by acitivity and set date to This year.

If anyone know a way to create a URL that leads directly to that report with those settings I would be very greatful for that info.

Unfortunately, without injecting some JavaScript, you cannot link directly to a report with pre-selected dropdown boxes, since they are not standard form fields with names and/or id's, rather they are just populated and driven by JavaScript.

You can only link directly to the result in JSON format, but you probably already know how to get it:

https://connect.garmin.com/modern/proxy/fitnessstats-service/activity?aggregation=lifetime&groupByParentActivityType=true&groupByEventType=false&activityType=running&startDate=2020-07-01&endDate=2020-12-10&metric=duration&metric=distance&metric=calories&metric=elevationGain&metric=elevationLoss&metric=avgSpeed&metric=maxSpeed&metric=avgHr&metric=maxHr&metric=avgRunCadence&metric=maxRunCadence&metric=avgBikeCadence&metric=maxBikeCadence&metric=avgPower&metric=maxPower&metric=avgVerticalOscillation&metric=avgGroundContactTime&metric=avgStrideLength&metric=avgStress 

Thanks.

I haven't investigated the services and exactly what they can provide so it is great info and can be useful if I attempt to develop something.
