When working with several languages, you may need to use a date format other than the one corresponding to the default language in Excel. Often, when you type a date in a cell in a particular format - such as dd-mm-yy (EN) or dd.mm.yy (DE) - Excel converts it automatically to the date format of the default language.
You can avoid this and make sure that the dates in your Excel worksheet remain exactly as you entered them.
- Select the cells or ranges in the worksheet where you want to apply a particular date format.
- From the Format menu select the Cells option.
- In the dialogue box that opens select Date in the Category field.
- In the Type field choose the date format you want.
- In the Locale field, select the corresponding language or language variety.
- Click OK.
