 Tempo is best thought of as a collection of utilities for working with `Date` objects — an important distinction from other libraries that provide custom date primitives. Under the hood, Tempo mines JavaScript's `Intl.DateTimeFormat` to extract complex data like timezones offsets and locale aware date formats giving you a simple API to format, parse, and manipulates dates.
 
+Tempo is tiny tree-shakable framework, you can only take what you need. All functionality is available in **5.1 kB for esm** and **5.4 kB for cjs** modules (minified and brotlied). [Size Limit](https://github.com/ai/size-limit) controls the size.
