Calling Methods with a Delay

Calling Methods with Delay — Hangfire Documentation

Sometimes you may want to postpone a method invocation; for example, to send an email to newly registered users a day after their registration. To do this, just call the BackgroundJob.Schedule method and pass the desired delay:

https://docs.hangfire.io/en/latest/background-methods/calling-methods-with-delay.html

Set the delay with a time span

BackgroundJob.Schedule(
    () => Console.WriteLine("Hello, world"),
    TimeSpan.FromDays(1));

HangFire Server by default polls the DB every 15 seconds, you can change the interval like this

var options = new BackgroundJobServerOptions
{
    SchedulePollingInterval = TimeSpan.FromMinutes(1)
};

var server = new BackgroundJobServer(options);
