How to Run Scheduled Tasks (Cron Jobs) in Go

Go does not have a built-in cron scheduler; you must use a third-party library like robfig/cron to run tasks on a schedule. Install the library and define your job function, then start the cron instance to execute it at the specified intervals.

import "github.com/robfig/cron/v3"

func main() {
    c := cron.New()
    c.AddFunc("0 0 * * *", func() {
        // Your task logic here
    })
    c.Start()
    select {}
}

Cron jobs are automated tasks that run at specific times, like a digital alarm clock for your code. Since Go doesn't include this feature by default, you add a small helper tool to your project that handles the timing for you. This lets your program perform maintenance or data updates automatically without manual intervention.
