Drop in the email, the group text, or the spreadsheet. Seasonkeeper reads the dates, shows you what it found, and gives you one link the whole team subscribes to. Move a game next month and every phone updates on its own.
No account. Nothing to install. Works with Apple Calendar, Google Calendar and Outlook.
Three problems, solved properly
"Jan 9, 16, 30" is three dates in January, not one date and some stray numbers. Prose, tab-separated junk out of a PDF, a CSV from the league: paste it and see what came back before anything is saved.
"Saturday, March 20" has no year in it. Guess wrong and you get a calendar that looks perfect and is twelve months off. Seasonkeeper scores each candidate year against the weekdays in your text and shows you which one actually fits.
Emailing a file means the first rain-out makes it a lie. People subscribe to a link instead. Change a date, press save, and it lands on every phone that subscribed without you telling anybody.
That is how people miss things. When your text names weekdays, Seasonkeeper uses them as evidence and tells you which year they actually fit.
You build a season twice a year. You should not rent it monthly.
