[Data-modeling] Date/Time type requires a specific year when all I want is to capture a yearly calendar event

[Gordon Mackenzie]

For Meteor Showers, there is a range of dates the shower occurs within  
and a peak date when the Zenithal Hourly Rate (the maximal number of  
meteors observed within an hour when observational conditions are  
optimal) is at its highest.

I could simply make the new properties, and give them the Text type.  
That seems a shame for I think it would be more useful to have a  
calendar year date-range type (either one that includes the option to  
just enter the hour/month/date with the ability to add a second set of  
values to form the range or two separate types, one for specific  
calendar date and one for range of calendar dates).

I've been informed this is a variant of an anniversary issue. Where it  
is not a simple task to get a MQL query result of say of that of an  
anniversary like all the people sharing a birthday in a instantly  
useable form.
