The null date type is the parent of all the other data types in Lasso. Every date type inherits the member tags of the null data type.

Null is the default value that variables are set to when they are first created. It can be useful as a comparison value and is equal to 0 and the empty string ''.

In the LDML Reference, all of the member tags of null can be used on values of any data type.

See the Lasso 8 Language Guide for examples of how to use this tag.
