day()
描述：
获取日期型数据中的日。
语法：
day(dt)
备注：
获取日期型数据dt的日。
参数：
|
dt |
表达式，可以是日期或日期时间格式的字符串，也可以是整数，为整数时可以理解为days@o()计算出的值。 |
选项：
|
@w |
从日期型数据中获取该日位于一个星期中的第几天，星期天返回1，星期一返回2，依此类推。 |
返回值：
整数
示例：
|
|
A |
|
|
1 |
=day(datetime("19800227","yyyyMMdd")) |
27 |
|
2 |
=day(datetime(12345)) |
1 |
|
3 |
=day(datetime("2006-01-15 10:20:30")) |
15 |
|
4 |
=day@w(datetime("19800227","yyyyMMdd")) |
返回值为4，表示星期三。 |
|
5 |
=day@w(datetime("2006-01-15 10:20:30")) |
返回值为1，表示星期日。 |
