You have the ability to update your Fiscal Year End (FYE) on Standard Metrics within Settings. Please follow the below steps to do so:
Navigate to the Settings tab on the left-side navigation panel.
You'll land on General settings. Scroll down to Preferences and find the Fiscal Year End section. Select from the Month and Day drop-down menu to update to the correct FYE.
No need to click save - your FYE will be updated, and the changes will be reflected on your/your investor's pages.
