One page. Every day starts unnamed. The first name of the day is free: type it, pick a colour and emoji, and the headline becomes "Today is ___ Day". After that anyone can take the day over from $2 and outbid by a dollar until midnight UTC, when the day is sealed into the archive. Outbid? Raise your claim and pay only the difference. Gift a day (birthdays, launches, inside jokes) with a certificate they keep. Names are screened automatically. Streamers get a free OBS overlay.
