# Timestamps and Resolutions ## **Timestamps** All metric timestamps are denoted in `UTC` and always refer to the **start of an interval****.** **Examples**: * **Monthly** resolution: `2019-05-01` --> Includes data from`2019-05-01 00:00 UTC` to `2019-05-31 23:59 UTC` (i.e. May 2019) * **Weekly** resolution: `2019-05-13` --> Includes data from `2019-05-13 00:00 UTC` to `2019-05-19 23:59 UTC` (i.e. Week 20) * **Daily** resolution: `2019-05-13`--> Includes data from`2019-05-13 00:00 UTC` to `2019-05-13 23:59 UTC` * **Hourly** resolution: `2019-05-13 10:00 UTC` --> Includes data from`2019-05-13 10:00 UTC` to `2019-05-13 10:59 UTC` * **10 Min** resolution: `2019-05-13 10:20 UTC` --> Includes data from `2019-05-13 10:20 UTC` to `2019-05-13 10:29 UTC` ## **Resolutions** Currently, Glassnode metrics as available in the following resolutions\*: * **1 month** (API param: `1month`) * **1 week** (`1w`) * **1 day** (`24h`) * **1 hour** (`1h`) * **10 minutes** (`10m`) Resolution means the **frequency** at which the data is being updated, as well as the **time window** over which a metric is being aggregated. For instance, the [**number of active addresses**](https://studio.glassnode.com/metrics?a=BTC\&category=\&m=addresses.ActiveCount) on a `24h` resolution shows the total number of active addresses over 24 hours (the **time window**). In addition, a new data point is provided once a day (the **frequency**). The same mechanism is applied analogously to all other resolutions. For metrics that show the current state of the blockchain rather than an aggregate over a window (e.g. the [number of addresses with a non-zero balance](https://studio.glassnode.com/metrics?a=BTC\&category=\&m=addresses.NonZeroCount)), the value refers to the time at the end of the interval. *\*All metrics are always available at a `24h` resolution. Whether other resolutions are available for a particular metric, depends on the metric and* [*your plan*](https://studio.glassnode.com/pricing)*.
