Time Series Data

Any data which has some temporal identity can be considered time series data.

Your internet data consumption every month, tracked over multiple months, would comprise time series data. If you record the distance your car has been driven every week over a long duration then you are creating time series data. Flagging every instance that you used the phrase, ‘So what else is up?’ on a phone call would also make time series data. Time series data, actually, is all around.
