早期年份的星期准确吗？Are weekdays right for early years?
准确。星期按外推格里高利历直接计算，0001-01-01 是星期一；年份标题按 4 位补零（如 0001-01）。1582-10 会提示 10 月 5–14 日在改历国家并不存在。Yes. Weekdays are computed on the proleptic Gregorian calendar, so 0001-01-01 is a Monday, and the title always uses a 4-digit year such as 0001-01. For 1582-10 a note says that 5 to 14 October never happened in countries that switched calendars.
和时区有关吗？Do time zones matter?
无关，月历只取决于年份和月份，不读取设备时钟。No. The calendar depends only on the year and month and never reads your device clock.
有哪些选项可以调整？What options can I adjust?
可以设置年份（默认 2026）、月份（默认 10）、每周开始于周一或周日（默认周一），以及背景色和文字颜色。改动后月历会重新绘制。You can set the year (default 2026), the month (default 10), whether weeks start on Monday or Sunday (Monday by default), and the background and text colours. The calendar is redrawn when you change any of them.
