SavvyCal — Time zone comparison

Calendar & SchedulingSee it livetime.savvycal.com

A large local time anchors a horizontal hour rail and comparison cards, making a time difference visible before users need to read a city list.

Calendar & scheduling

Why this pattern works

Public time zone converter.

Design notes

Surface: Public time zone converter.
Navigation: Time and zone selectors across the top, plus a Share action.
Layout: Large date and time, horizontal timeline, then city comparison cards.
Density: Low around the current time, denser further down the city list.
Color: Warm cream, dark navy, white cards, green primary utility action.
Type: Large tabular-looking time numerals with compact sans labels.
Pattern: Establish one reference time and show the offset beside every comparison.
States: Live current-time state; this capture does not book or share a meeting.
Don't: Do not rely on zone abbreviations alone when a city and relative offset can clarify them.

## Acceptance criteria
- Existing project conventions, design tokens, working functionality, and unrelated changes are preserved.
- Two or three reference principles clearly support the user's task; conflicts are resolved in favor of usability and the existing product.
- Reusable components and semantic HTML express the interface. Available licensed assets are used; important UI text is never rendered as a bitmap.
- Every visible control has a defined behavior. Loading, empty, error, success, disabled, and long-content states are specified where relevant. Demo data is clearly labeled.
- Navigation and content adapt at 375px, 768px, and 1440px without horizontal page overflow. Keyboard use, visible focus, labeled inputs, at least 44px touch targets, readable contrast, and reduced motion are supported.
- Verification distinguishes rendered behavior from proposals and identifies anything still requiring a backend or external service.

## Quality bar
Clear hierarchy, consistent spacing, restrained surfaces, and purposeful motion. Avoid decorative gradients, excessive cards, placeholder buttons, and invented metrics unless the project calls for them. Do not claim a feature is connected or tested without evidence.
