Family Tree Builder provides a rich variety of options for entering dates or ranges of dates.
To enter a date, either type it into the field using any format that you like (free text) or click the Date icon that appears on the right of each date field.
The following window is displayed:
Hebrew and French Revolution Calendars
This window also enables you to click the Hebrew Calendar button or the French Revolution Calendar button at the bottom of the window in order to display the required calendar. You can then make your selections in this calendar in the same way as in the Standard Calendar (Georgian calendar).
If you would like, you can convert this date into the corresponding date in the standard calendar by clicking the Convert button.
Click on the OK button to save your changes.
