$DATECHK(format, date)

where:
<ul>
<li>format specifies the format of the date, which can be a combination of the following elements:</li>
<table>
<tr>
<td>DD</td>
<td>Gregorian numeric day</td>
</tr>
<tr>
<td>DDD</td>
<td>Julian numeric date</td>
</tr>
<tr>
<td>MM</td>
<td>Numeric month</td>
</tr>
<tr>
<td>MON</td>
<td>Abbreviated month name</td>
</tr>
<tr>
<td>MONTH</td>
<td>Full month name</td>
</tr>
<tr>
<td>YY</td>
<td>Last two digits of numeric year (assumes that the year prefix is 19)</td>
</tr>
<tr>
<td>YYYY</td>
<td>Full numeric year </td>
</tr>
<tr>
<td>CYY</td>
<td>The century, plus the year. Century (C) is a single digit, where 0 represents 1900, 1 represents 2000, and so on.</td>
