生活 ツール
Daily life utilities: dates, age, decisions, recipes, journals.
カテゴリー紹介
Not every tool fits a clean category. Life tools are the in-between utilities: counting days until an event, calculating exact ages, picking what to eat tonight, journaling for gratitude or mood tracking. Small tools, big quality-of-life impact.

よくある質問
Are journal entries private?
Yes — gratitude and mood journal entries live in your browser's localStorage. No server, no account, no sync. Export as JSON if you want backup.
How is age calculated across time zones?
We use your browser's local time zone by default. For legal use cases (passport, court documents), confirm the relevant jurisdiction's definition — most use civil time in the person's place of birth.
Can I count business days only?
The date difference calculator offers a business-day mode that excludes weekends. Holiday calendars aren't built in — adjust manually for major holidays in your region.
