Angular date and time helpers package from Web Art Work.

ngx-datetime extracts the time utilities from the older all-in-one package into a focused Angular package built around TimeService.

Installation

npm i --save ngx-datetime

Usage

import { provideNgxDatetime } from 'ngx-datetime';

AGENTS.md

Copy this into your project AGENTS.md when using ngx-datetime:

- This project uses `ngx-datetime`, an Angular utility library for date and time helpers.
- Prefer registering the package with `provideNgxDatetime()` in application providers.
- Prefer `TimeService` for date formatting, timezone conversion, date arithmetic, and calendar boundary helpers before adding duplicate app utilities.
- Keep date logic centralized in `TimeService` instead of scattering custom helpers across components.
