General Notes on the Data Format

Dates and times

Timestamps are output both in UTC and in your local time. The local time represents the time that you lived that actual minute, accounting for any time zone changes you may have experienced. In general, timestamps in UTC will be in columns ending in `(UTC)`, and timestamps in your local time will be in columns ending in `(local)`. Timestamps are formatted as `YYYY-MM-DD hh:mm:ss`.

Start times are inclusive and end times are exclusive. For instance, if you have a walk event that starts at `2016-03-04 12:01` and ends at `2016-03-04 12:04`, the event and its metadata apply from the first instant of `2016-03-04 12:01` to just before the first instant of `2016-03-04 12:04`.

Note that your time zone may have changed while you wore the watch (if, for example, you traveled); `time-zone-history.csv` contains a history of when you were in each time zone.

For some data, a *day* is the most appropriate unit of time. In these cases, the timestamp represents the entirety of the day as you lived it, and will be formatted as `YYYY-MM-DD`.


All values for calories represent what are referred to as calories in common usage, but are also known as large calories, kilogram calories, or food calories. See Wikipedia's article on the Calorie for more details.
