Hours of Operation is one type of Business Data that we store and use to synchronize to your website and, ultimately, other profiles across the internet.
When you update your Hours of Operation it will update anywhere it appears on your website - assuming you're using Locable's web-builder or website integration features.
Start by clicking Company Data > Business Hours
Make changes to existing Hours or add and remove openings.
Once your changes are made, be sure to click 'Save' so these changes will be saved and updated on your site.
