Word to describe a time interval

When a magazine subscription is about to expire the publisher sends a notification to the subscriber. The notification is usually sent a month before expiration, however this value varies based on the subscriber profile. Is there an English word to describe this value?


Not a single word but the term notice period comes to mind:

[Cambridge dictionary]
notice period (noun)
- the period between the time that you are told about something and the time that it must happen or be done


Renewal Notice -or- Renewal Period

Another option not a single word, but it may fit better specifically with subscriptions.

renewal Miriam-Webster

renewal noun

Definition of renewal

3 : something (such as a subscription to a magazine) renewed

In some cases this before your subscription expires and sometimes it is where they send you "just one more" periodical, extending the contract beyond what you originally paid.

renewal The free dictionary

n. keeping an existing arrangement in force for an additional period of time, such as a lease, a promissory note, insurance policy or any other contract. Renewal usually requires a writing or some action which evidences the new term.


Coming from a more technical background, one could refer to the Notification Window, where the term "window" is used as indicated in this meaning from the Free Dictionary:

  1. An interval of time during which an activity can or must take place: a window of opportunity for a space mission; a window of vulnerability when the air force was subject to attack.

Also an expression and not a single word:

time limit

A limit of time within which something must be done.
