ICS viewer
Paste any calendar feed link (.ics or webcal://) and see what is inside: every event for the next 12 months, in your browser, no signup. Useful for checking a league or school feed before you subscribe to it.
What this shows you
An ICS feed is the standard way calendars are published on the internet: a plain-text list of events that apps like Apple Calendar, Google Calendar, and Outlook can subscribe to. The trouble is that a feed URL tells you nothing about what is inside it. This viewer fetches the feed and lays out every event, so you can confirm a league schedule is current, check whether a school feed includes the holidays, or debug a feed you publish yourself.
The viewer expands recurring events, honors skipped dates, and flags events whose end times are missing, which is one of the most common problems in hand-built feeds. Everything happens on our servers; nothing is stored, and no account is needed.
