把公共时间放进你的日历
Almanac 历书是一个 iPhone 日历：你的日程照常存放在系统日历里，同时可以订阅由「历官」维护的公共日历——法定假日、传统节日与节气、各国假日、央行议息、体育赛事、科技发布会……与私人日程叠加显示。
日、周、月、年四种视图
直接读写系统日历，支持新建、编辑、拖拽、重复事件与搜索；中文用户默认显示农历。
历的市场

每份历可单独设置「全部 / 仅重要 / 关闭」通知，全天事件前一天 20:00、定时事件前 30 分钟提醒。
不需要账号
没有注册、没有广告、没有统计 SDK。你的日程不会离开设备。
Public time, in your calendar
Almanac is an iPhone calendar. Your own events stay in the system Calendar, and you can subscribe to public calendars kept by curators — public holidays, traditional festivals and solar terms, central-bank meetings, sports seasons and tech events — shown alongside your schedule.
Day, week, month and year
Reads and writes the system Calendar: create, edit, drag, recurring events and search. Chinese lunar dates are available as a secondary calendar.
A market of calendars
Browse by category, search, preview the next 30 days, then subscribe or unsubscribe in one tap. Each calendar names its sources and is signed with Ed25519 so tampering is detected.
Only the reminders you want
Choose All, Important only or Off per calendar.
No account needed
No sign-up, no ads, no analytics SDKs. Your events never leave your device.
