Say dates are normally used when you compute a date from other events
WITHOUT specific information. For instance you know the year a couple
marries, but have no information on when there children were born, but know
the birth order. You can enter say dates of Marriage+2, +4, ... for their
birth. Or vice versa, you know when (some of) the children were born you can
guess with a say date when the marriage might have been, and maybe when some
of the other children were born.
When you have events with ages, then GEDCOM standard suggests using a "calc"
modifier, but in the example when there is minor conflict on the exact year
a circa/about prefix can make sense also.
