Celery : Execute task after a specific time gap

I want to send an email to my users exactly 48 hours after they have registered.How do i achieve this using celery? If I create a periodic task to send an email, I will have to decide a specific time during which i want to execute that task. I don't want to keep run a celery task every second to check if there are any emails needed to be sent.

You'll want to make use of ETA. Read that section of the docs as it'll have more information. However, your code will look something like this:

from datetime import datetime, timedelta
send_date = datetime.utcnow() + timedelta(days=2)
email_user.apply_async([user], eta=send_date)
