How we count seats

Seats on the map. Every reserved seat on the event's seat map, with a section, a row and a number. The map belongs to one event, so two shows at the same venue can have different totals.

On sale. A seat you could buy from the primary market at that moment.

Taken. A seat on the map that was not on sale. Taken covers seats people bought and seats the promoter or the artist kept off sale.

Released. Seats that went on sale for the first time in a sale window.

A sale window is one presale or the general sale, with the minute it opened. Windows that open at the same minute count as one window, because they put seats on sale at the same moment. A window that opens later than another runs until the next one opens.

Def Leppard and Goo Goo Dolls at TD Garden lists 6 windows, each with the seats it released.

The chart on an event page shows primary seats on sale over time, up to Nov 7, 2026. The numbered marks on the chart are the sale windows, in the order they opened.

Counts are as of Nov 7, 2026. Event dates and window times are in the venue's local time.
