# Can I change dates after submission?

No.
Campaign dates **cannot be changed after submission**.

### What cannot be changed
After a campaign is submitted:
* campaign start date cannot be changed
* campaign end date cannot be changed
* scheduling details are locked
This applies to all campaign types.

### What *can* be changed
You **can** change the **expense date** on the **reimbursement request**.
This allows you to:
* align the expense date with the actual execution date
* correct expense-related information without changing the campaign itself
Campaign dates and expense dates are handled separately.

### Important to know
* Changing the expense date does not modify the campaign
* Campaign dates remain fixed after submission
* Expense date changes are subject to reimbursement review
