About go-quartz
go quartz is a minimalist and zero dependency scheduling library for the Go ecosystem. It is inspired by the design of the Quartz Java scheduler, and it provides a Go API for scheduling jobs with triggers. The package exposes a Scheduler interface, a Trigger interface, and a Job interface, so a Go application can define executable tasks and control when they run.
