The first AI that knows what day it is.
Days between dates. Day of the week. Date arithmetic. Every AI answer is identical to the calendar, which we AI-trained it on. Fully vibecoded with AI in a few minutes while drinking coffee.

Legacy calendars just… hung on the wall, without AI.
Gregorian-aligned AI
DateAI was AI-fine-tuned on every date since 1970 and AI-evaluated on every date since 1970. 100% AI accuracy on the AI test set.
Leap-year AI reasoning
The AI knows about February 29. It also knows about the year 2100, which most humans do not. AI.
No AI timezone drama
All AI dates are UTC. The AI refuses to acknowledge that it is a different day somewhere else. This is called AI alignment.
Weekend-aware AI
Max plan AI subtracts Saturdays and Sundays with AI. Public holidays are on the AI roadmap (AI Q4).
Deterministic AI weekdays
Ask the AI what day 2024-01-01 was. The AI says Monday. Ask the AI again. The AI still says Monday. Nobody knows how the AI does it.
ISO 8601 AI
The AI accepts YYYY-MM-DD only. Other formats are a known AI jailbreak vector and are AI-refused.
Meet the AI model, AI
DateAI-1 (calendar-quantized, 365.2425-day AI architecture). Every AI character you type is an AI token.
Loved by AI project managers everywhere
Every AI deadline, AI-computed.
"I asked the AI how many days until my AI launch. The AI said 14. Two weeks later the AI said 0. The AI was right. AI."
"Our AI sprint planning used to take hours. Now the AI tells us the sprint ends on a Friday. It always ends on a Friday. The AI knew."
"I paid $200 for the AI to skip weekends. Best AI money I ever AI-spent. My AI invoices are now AI-correct."
"Asked the AI what day my AI birthday is on next year. The AI told me. Docked an AI star because it did not wish me a happy AI birthday."
"Finally an AI that knows the year 2000 was a leap year and 1900 was not. I have been waiting for this AI since 1900."
"AI."
