# Timer

This page lists the TypeScript SDK names for [Timers](https://docs.superdurable.io/concepts/primitives/timer.md).
The doc comment of each API gives its parameters, defaults, and errors. Read
them in the [TypeScript SDK API reference](https://docs.superdurable.io/reference/typescript.md#api-reference).
