Calendar & Schedule

1. Overview

The Calendar & Schedule tab is the second page in the bottom navigation bar. It integrates the calendar and schedule management — you can browse the calendar (month/week view) and see what’s planned for each day.

Core features:

Browse calendar: The month view shows lunar dates, solar terms, and public holidays (labeled “Work/Off”). Schedule bars appear directly in the date cells
View schedules: All schedules for the current day and selected dates are listed below — see what’s planned at a glance
Add schedule: Tap the yellow + button in the bottom-right corner to quickly create a to-do with the selected date’s start/end time pre-filled
Manage schedules: Tap a schedule to edit it; long-press for a menu to complete/restore, edit, or delete
Sync third-party calendars: Supports WeCom, DingTalk, Feishu, Exchange, CalDAV, and Microsoft Calendar for unified viewing
Write to system calendar: Schedules from the app can sync to each platform’s system calendar

2. Display

Three Calendar Collapse States

The calendar area can be switched between three modes by swiping vertically (up/down). The schedule panel at the bottom changes accordingly:

State	Calendar Display	Schedule Panel
Full mode	Month view + lunar/solar term text below each cell	Collapsed to show only a small arrow icon
Normal mode	Month view (schedule dots shown in cells)	Shows current day’s schedule list
Compact mode	Week view (only one week shown)	Shows entire month’s daily grouped schedule list, scrollable

Switch between the three modes by dragging vertically on the calendar area: dragging down to enlarge the calendar moves toward full mode; dragging up to shrink it moves toward compact mode. It automatically snaps to the nearest state when released.

Month View Cells

Each date cell displays from top to bottom:

Top-right small text: Public holiday label — orange “Work/Makeup” or green “Off” (synced from server, Chinese region only)
Center large date number: Today is highlighted with a yellow-outlined circle; the selected day is a yellow-filled circle
Lunar/solar term below (full mode + Chinese interface only): Priority order: Gregorian holiday → Lunar holiday → Solar term → Lunar date (no more than 3 characters)
Schedule dot (normal/compact mode): A small dot appears below the date number when the day has schedules

The week header shows “Mon, Tue, Wed, Thu, Fri, Sat, Sun.”

Schedule List (Bottom Panel)

The schedule list appears in a white rounded panel at the bottom. Each schedule’s layout:

┌─────────────────────────────────────────┐
│  All-day  ┃  Weekly Team Meeting         │
│           ┃                              │
│  14:00    ┃  Product Review              │
│  15:00    ┃                              │
│           ┃                              │
│  All-day  ┃  Business Trip (completed     │
│           ┃   items show strikethrough)   │
└─────────────────────────────────────────┘

Left time column: All-day schedules show “All-day”; scheduled items show “HH:mm / HH:mm”; middle days of multi-day events show “All-day”
Yellow vertical line: The divider between time and content (always yellow)
Content area: Shows the schedule title (bold 16px)
Source label: Shows the source name at the bottom, e.g., “Calendar: YYNote” or “Calendar: Microsoft Calendar”
Third-party calendars: Shows “Third-party calendars do not support editing or sync” notice
Completed: Title text turns gray + strikethrough

In normal mode, the bottom panel shows only the selected day’s schedules; in compact mode, it shows each day’s grouped schedules for the month (grouped by date, each group header shows date + lunar date).

Different States

State	Display
No schedules today	Bottom panel is empty, no “No schedules” prompt shown
All schedules completed today	All schedules shown in gray with strikethrough
A day is selected	Date cell turns into a yellow-filled circle
Today	Date cell turns into a yellow-outlined circle (does not stack with selected state)
