These are the fields in the Site Information card at the top of Settings › General in the admin. Changes here don't apply until you click Save Settings at the bottom of the page.
This is in reference to your program's site.
The name of the program itself, which isn't always word-for-word your site name.
This displays the main URL for your program. There are other URLs when linking off to the prize store or a member's activity page, but they all hang off this main one. You can change it at any time — for example, if you decide to rebrand your program you may need to change the main URL as well.
This is the single most consequential field on the page. Every date and time the admin shows you is rendered in the timezone you set here — event start and end times, report windows, order timestamps, all of it. If your program is based in the Central Time Zone, set Central here, and an event you schedule for 7pm is 7pm Central.
The Timezone field is a searchable picker rather than a plain dropdown. Click it and start typing: it matches on city, zone name and abbreviation, so "chicago", "central" and "CST" all land on the same row. Zones are grouped by region with US & Canada first.
The date season totals are computed from.
