<p id="par_id3147229" class="paragraph" dir="auto">
<span class="emph">Year:</span> Integer expression that indicates a year. All values between 0 and 99 are interpreted as the years 1900-1999. For years that fall outside this range, you must enter all four digits.</p>
<p id="par_id3156280" class="paragraph" dir="auto">
<span class="emph">Month:</span> Integer expression that indicates the month of the specified year. The accepted range is from 1-12.</p>
<p id="par_id3151043" class="paragraph" dir="auto">
<span class="emph">Day:</span> Integer expression that indicates the day of the specified month. The accepted range is from 1-31. No error is returned when you enter a non-existing day for a month shorter than 31 days.</p>
<p id="par_id3161832" class="paragraph" dir="auto">The <span class="emph">DateSerial function</span> returns the number of days between December 30,1899 and the given date. You can use this function to calculate the difference between two dates.</p>
<p id="par_id3155306" class="paragraph" dir="auto">The <span class="emph">DateSerial function</span> returns the data type Variant with VarType 7 (Date). Internally, this value is stored as a Double value, so that when the given date is 1.1.1900, the returned value is 2. Negative values correspond to dates before December 30, 1899 (not inclusive).</p>
<p id="par_id3152576" class="paragraph" dir="auto">If a date is defined that lies outside of the accepted range, LibreOffice Basic returns an error message.</p>
<p id="par_id3149481" class="paragraph" dir="auto">Whereas you define the <span class="emph">DateValue function</span> as a string that contains the date, the <span class="emph">DateSerial function</span> evaluates each of the parameters (year, month, day) as separate numeric expressions.</p>
