# Features

Cakeday organizes birthday management into capture, reminders, sync, and Apple platform integrations. Use this overview to find the right area, then open the detailed guide for setup steps and edge cases.

## Capture and Organize

[Birthday Management](/docs/en/birthday-management)

Save names, dates, avatars, notes, groups, birth time, birth city, and timezone details, with automatic age and countdown calculation. Each friend's detail page also opens a **Birthday Almanac** with year-by-year insights and a weekday spread for every birthday.

[Groups](/docs/en/groups)

Organize friends by family, friends, coworkers, or any custom structure. Each group supports its own name, color, icon, and sort order.

[Lunar Calendar](/docs/en/lunar-calendar)

Record birthdays on the traditional Chinese lunar calendar, including solar-lunar conversion and leap month handling.

[Zodiac & Astrology](/docs/en/zodiac)

Cakeday shows Western zodiac and Chinese zodiac information, and can calculate the Ascendant when birth time and city are provided.

## Reminders and Surfaces

[Notifications & Birthday Alarm](/docs/en/notifications)

Start with the full reminder system, including reminder offsets, Time Sensitive delivery, Communication Notifications, friend-timezone reminders, and Birthday Alarm.

[Birthday Alarm](/docs/en/birthday-alarm)

Set alarm-style birthday reminders for important friends with sound, timing, and optional HQ sound downloads.

[Widgets, Controls & Apple Watch](/docs/en/widgets)

See upcoming birthdays on the Home Screen, in Control Center, and on Apple Watch, with quick add, next birthday, and per-person countdown surfaces.

## Sync and Sharing

[iCloud Sync](/docs/en/icloud-sync)

Sync birthday records and groups across Apple devices with your Apple ID and Apple private CloudKit database.

[CakeShare](/docs/en/cakeshare)

Share one record by deep link, or export protected `.cakeshare` files for larger transfers with optional password protection.

[Backup & Import](/docs/en/backup-import)

Use full `.cakeday` backups, JSON/CSV export, and `.cakeshare` import with duplicate detection and progress feedback. **Import from Apple Contacts** to pull names, birthdays, and avatars from friends you allow — Cakeday never modifies your contacts.

## Platform and Settings

[Appearance & Display](/docs/en/appearance)

Choose accent colors, appearance mode, lunar display, 24-hour time, date formats, and optional astrology details.

[Spotlight, Siri & Shortcuts](/docs/en/spotlight-and-shortcuts)

Find, add, or review birthdays from system search, Siri, and Shortcuts.

[System Calendar Sync](/docs/en/system-calendar-sync)

Write selected birthdays into the system Calendar and keep annual recurring events updated.

[Accessibility](/docs/en/accessibility)

Review support for Dynamic Type, VoiceOver, Reduce Motion, and system appearance preferences.
