# Effective Dates, Expiry Dates, and Grace Periods
### Effective Dates, Expiry Dates, and Grace Periods
These are usually cosmetic discrepancies. The Grace Period field is the key — it lets you filter out the inevitable one or two day offsets that aren't real issues.
{% stepper %}
{% step %}
### Filter effective date mismatches
Check the box for **Effective Date** to filter for mismatched lease effective dates.
{% endstep %}
{% step %}
### Set a Grace Period
Enter a number in the **Grace Period** field (e.g., 1) to ignore discrepancies caused by expected one-day offsets for Expiry and Extension Dates
{% hint style="info" %}
The Grace Period field applies to **three** filters: Effective Date, Expiry Date, AND Extension Date. Set it once when you start your review and forget about it.
{% endhint %}
{% endstep %}
{% step %}
### Review Expiry Date Differences
Check the **Expiry Date** box and search to review differences in expiration dates between the systems.
{% hint style="warning" %}
Expiry Date here is the original expiry — not what the lease has been extended to. Mismatches usually won't make or break a lease. And sometimes the expiry is entered loosely (e.g., as the end of the intermediate term), so the date might look off but the substance is fine. Spot-check before raising flags.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.stackdx.com/untitled/resolving-discrepancy-types/effective-dates-expiry-dates-and-grace-periods.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
