### វាក្យ​សម្ពន្ធ​​

DAYS(កាលបរិច្ឆេទ 2; កាលបរិច្ឆេទ 1)

កាលបរិច្ឆេទ 1 គឺ​ជា​កាលបរិច្ឆេទ​ចាប់ផ្ដើម, កាលបរិច្ឆេទ 2 គឺ​ជា​កាលបរិច្ឆេទ​បញ្ចប់ ។ ប្រសិន​បើ កាលបរិច្ឆេទ 2 គឺ​ជា​កាលបរិច្ឆេទ​មុន កាលបរិច្ឆេទ 1 គឺ​ជា​ចំនួន​អវិជ្ជមាន ។

When entering dates as part of formulas, slashes or dashes used as date separators are interpreted as arithmetic operators. Therefore, dates entered in this format are not recognized as dates and result in erroneous calculations. To keep dates from being interpreted as parts of formulas use the DATE function, for example, DATE(1954;7;20), or place the date in quotation marks and use the ISO 8601 notation, for example, "1954-07-20". Avoid using locale dependent date formats such as "07/20/54", the calculation may produce errors if the document is loaded under different locale settings.

Unambiguous conversion is possible for ISO 8601 dates and times in their extended formats with separators. If a #VALUE! error occurs, then unselect Generate #VALUE! error in LibreOffice - PreferencesTools - Options - LibreOffice Calc - Formula, button Details... in section "Detailed Calculation Settings", Conversion from text to number list box.

### ឧទាហរណ៍
