| 235 | * Excel interprets the year argument according to the configured |
| 236 | * date system: 1900 or 1904. |
| 237 | * If year is between 0 (zero) and 1899 (inclusive), Excel adds that |
| 238 | * value to 1900 to calculate the year. For example, DATE(108,1,2) |
| 239 | * returns January 2, 2008 (1900+108). |
| 240 | * If year is between 1900 and 9999 (inclusive), Excel uses that |
| 241 | * value as the year. For example, DATE(2008,1,2) returns January 2, |
| 242 | * 2008. |
| 243 | * If year is less than 0 or is 10000 or greater, Excel returns the |
| 244 | * #NUM! error value. |
| 245 | * @param int $month A positive or negative integer representing the month of the year |
| 246 | * from 1 to 12 (January to December). |
| 247 | * If month is greater than 12, month adds that number of months to |
| 248 | * the first month in the year specified. For example, DATE(2008,14,2) |
| 249 | * returns the serial number representing February 2, 2009. |
| 250 | * If month is less than 1, month subtracts the magnitude of that |
| 251 | * number of months, plus 1, from the first month in the year |
| 252 | * specified. For example, DATE(2008,-3,2) returns the serial number |
| 253 | * representing September 2, 2007. |

| 255 | * from 1 to 31. |
