# Key Dates

Aside from expiries, renewals, and notification periods, Aerofiler can also track key contractual dates. For example, suppose you have an insurance document expiring on 31 October 2022. In the single file view, scroll down to the “Key Dates” section and click “Add Key Date”:

Then enter the date and a description and click “Save”:

The key date should appear as follows:
