nove31 is a free Chrome add-on developed by paolo. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This add-on allows users to calculate their work hours and predict their expected time of departure.

nove31 retrieves timestamp data from the attendance portal every time the page is opened, changed, or refreshed. This means that every time you clock in or out, the add-on will update accordingly.

If no timestamps are entered, nove31 will notify you (this feature can be enabled or disabled in the settings) if you are browsing pages other than the attendance portal, reminding you to clock in for the first time.

With one timestamp entered, nove31 provides a button to simulate a lunch break (the duration of which can be configured in the settings) and calculates the expected time for the final timestamp.

With two timestamps entered, nove31 functions similarly to when no timestamps are entered. If notifications are enabled, it will alert you if you are browsing without having made the third timestamp.

When three timestamps are entered, nove31 displays the predicted time for the final timestamp in order to reach 8 hours.
