## What it is
go-quartz is a minimalist, zero-dependency job scheduling library for Go, inspired by the Quartz Java scheduler. It provides a Scheduler interface for managing jobs with triggers, including full Quartz cron expression support usable independently.

## Use cases
- schedule recurring jobs in a Go application
- run cron-style scheduled tasks with cron expressions
- pause, resume, and delete scheduled jobs at runtime
- compute next fire times from cron expressions
- run a distributed job scheduler across multiple instances

## When to choose
- you need a lightweight, dependency-free scheduler in Go
- you want Quartz-like cron semantics and job lifecycle management
- you need programmatic control over scheduled jobs (pause/resume/delete)

## When to avoid
- you need a standalone cron daemon or external task queue system
- you need persistence-backed distributed scheduling out of the box
- your project is not written in Go

## Facets
- artifact type: library
- maturity: active
- function: scheduling, workflow-automation, developer-tools
- domain: backend, developer-tools
- platform: go, cross-platform
- tags: job-scheduler, cron, quartz-inspired, zero-dependency, task-scheduling, job-queue, automation
