The fastest, cleanest way to view every country's calendar.

Date answers should be instant.

Calendars, public holidays, and time zones are questions billions of people search daily. The answer should arrive in under a second, on any device, anywhere — without ad clutter or dense tables.

Six rules guiding every page.

• 01Speed-first: each page feels instant, faster than you can perceive the load.
• 02Mobile-first: cards, not tables. Large tap targets. Single column on phone.
• 03Answer-first: the primary answer is above the fold. Details follow.
• 04Real localization: every country gets its own first-day-of-week, date format, and holiday list — not a translation layer.
• 05Full dark mode: not a CSS swap, but a palette designed as a first-class citizen.
• 06Honest about data: no fake ratings, no made-up numbers. Every figure has a source.
