FAQ
Common questions about Daynum
How does it work?
Uses the current date plus your custom word to generate the same number for everyone on the same day. Different words create different sequences.
Why the same number each day?
Consistency. Everyone gets the same number on the same date, making it useful for shared goals or coordination.
What does my custom word do?
Changes your number sequence while keeping it predictable. Same word + same date = same number.
Can I see future numbers?
Only tomorrow's number when it's already tomorrow somewhere in the world.
Is my word stored anywhere?
No. It's only used for calculation and not saved on any server.
Why 1-100?
Good range for most use cases - percentages, progress tracking, simple decisions.
Works offline?
No. Server validation prevents future key prediction and ensures cryptographic integrity.
Is this cryptographically secure?
Yes. Uses SHA-256 hashing with server-side salt protection. Numbers are mathematically unpredictable yet perfectly reproducible.
Can I use this for team coordination?
Perfect for it. Same date = same number worldwide. Great for synchronized challenges, meeting ice-breakers, or daily team goals.
What about creative applications?
Numbers work great as intensity scales: 1-20 for light creative sessions, 80-100 for ambitious projects.
