- Package: [@gooddata/sdk-model](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/index.md)
- Kind: type-alias
- Stability: alpha
- Source: https://github.com/gooddata/gooddata-ui-sdk/blob/rel/11.64/libs/sdk-model/src/base/granularityRegistry.ts

> **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md).
> 

Structural family of a date granularity.

**Signature:**

```typescript
export type GranularityFamily = "chronological" | "generic";
```

## Remarks

- `chronological` — sequential periods (year, quarter, month, week, date, hour, minute) and their fiscal variants. - `generic` — "X of Y" periods that repeat (month of year, day of week, …); a.k.a. cyclical/periodical.
