GenoDate Class

The GenoDate class encapsulates a date. This object is present where a date involved in GenoPro such as the birth date, death date, wedding date, etc. The GenoDate object has properties only, and consequently, you cannot modify it.

Property	Description
`Anniversary`	Returns a new `GenoDate` object without the year. If the date was empty or the year was missing, the returned `GenoDate` object is identical to its source. The `Anniversary` property may be useful to create a calendar of birthdays or remembering special events.
`Century`	This is very similar to the `Decade` property. This property was added to offer the option to group events and/or objects by century.
`Day`	Returns the day of the date or an empty string if the day is not present. Valid values ranges from `""`, `"1"` to `"31"`.
`Decade`	Returns the decade year of the date or an empty string if the year is not present. If the year is valid, last digit is always a zero. This property may be useful to group events and/or objects by decade. For instance, you may want to generate a picture album for the 60's, 70's, 80's, 90's, etc.
`FormatDateSpan(Date)`	Returns the duration between the date and another specified date.
`Month`	Returns the month of the date or an empty string if the month is not present. Valid values ranges from `""`, `"1"` to `"12"`.
`NDay`	Returns the day of the date as a number. 0 if the day is not present.
`NDayOfWeek`	Returns the day of the week (1=Monday, 7=Sunday). Returns zero if the weekday cannot be computed because the date is empty or incomplete.
`NMonth`	Returns the month of the date as number. 0 if the month is not present.
`NYear`	Returns the year of the date as number. 0 if the year is not present.
`SystemDate`	Returns a date compatible with the operating system
`ToString(String)`	Convert the date into a string based on a template.
`ToStringNarrative`	Convert the date into a string based on the local system date time is defined (Control Panel).
`Year`	Returns the year of the date or an empty string if the year is not present. Valid values ranges from `""`, `"0000"` to `"9999"`. The year is expressed in four digits, so year AD 476 would be expressed as `"0476"`

Usage:
The GenoDate object is user-friendly as it returns a string rather than a number. By having an empty string when a value is not present, it is possible to use "sandwich" methods such as Write3, Write3Br, WriteText3, WriteT3, and so on. A "sandwich method", such as Write3, does write the first and last parameter only if the middle parameter is non-empty. The following example writes to the output report "Year of Birth: " followed by the year of birth in bold. If the year of birth is empty, then this routine does not write anything to the output stream.

Report.Write3 "Year of Birth: <b>", i.birth.date.year, "</b><br />"

You could also use Write3Br to produce the same result:

Report.Write3Br "Year of Birth: <b>", i.birth.date.year, "</b>"
