每个格子代表什么？What does each box mean?
每格一周，一行约一年（52 周）；深色是已经度过的周。Each box is one week and each row is about a year (52 weeks); the dark boxes are weeks already lived.
可以输入哪些日期和年数？Which dates and spans can I enter?
出生日期须真实存在（如 2001-02-29 会报错），出生年 1900–2100；年数为 1–100 的整数，超出范围会提示错误，不会悄悄改值。The birth date must exist (2001-02-29 gives an error) and the birth year must be 1900 to 2100. Years must be a whole number from 1 to 100; values outside that give an error instead of being changed silently.
“已度过”是怎么算的？How are lived weeks counted?
用今天（设备时钟的当前时刻）减去出生日期 00:00 UTC，按整周计；出生日期在未来时为 0，超过所选年数时格子全部填满并给出提示。From the birth date at 00:00 UTC to the current moment on your device clock, in whole weeks. It is 0 for a future birth date, and if more than the chosen span has passed every box is filled and a note says so.
有哪些选项可以调整？What options can I adjust?
可以设置出生年月日（默认 1990-01-01）、年数（默认 90），以及背景、已过、未来和文字的颜色。改动后图会重新绘制。You can set the birth date (default 1990-01-01), the number of years (default 90) and the background, lived, future and text colours. The grid is redrawn when you change any of them.
