Question

This is the use case I am looking for :

It is a note making and remainder application
While creating remainder users will enter the time my application wants to send user an email at that time
I have to use celery for the same I read several posts and stack overflow answers but didn't get proper answer for the same.

My application is written in Django.

When a user creates a new reminder just schedule a send email task in celery. Note that this is a simple solution but it will make it hard for the user to change notification time after creating it.

From this answer:

To execute a task at a specified date and time you can use eta attribute of apply_async while calling task as mentioned in docs

your_task.apply_async(kwargs={}, eta="your_send_time")

A different solution is to have a task running every 1 minute which will check in DB if there are any emails to be sent. You don't have to use Celery for that. Cron-like lib should do the trick. For example schedule lib or django-cron or Django Commands

Edit: this guy says you should not use dbader/schedule with Django.
