# Timestamps and Resolutions

## **Timestamps**

All metric timestamps are denoted in `UTC` and always refer to the <mark style="background-color:green;">**start of an interval**</mark>**.**

**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)*. For a full overview of which metric is currently available a what resolution, please refer to our* [***Metrics Catalogue***](/introduction/metric-catalog.md)***.***

{% hint style="info" %}
The Advanced [Light API](https://docs.glassnode.com/basic-api/api#light-api) serves daily (`1d`) resolution only, which can differ from the resolutions available to the same plan in Glassnode Studio.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.glassnode.com/data/timestamps-and-resolutions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
