If your listing has an active rental currently or in the future, the calendar tool automatically displays those dates as unavailable (greyed-out). However, if your gear is unavailable for reasons not having to do with ShareGrid (such as repair, other rentals or for your own use), you can unavailable dates for that particular listing. Simply go to the listing’s page. Select “Edit listing”. Scroll to the bottom of the page and select “Add time period.” This will bring up a calendar window where you can select the dates this particular item is unavailable. You can create multiple time-frames as well by selecting “Add time period” for as many as you need.
