The images below show an example of use of the Birth Date Calculator.
To use you must Download or Run
|
|
| Enter an event date (or select a UK census date) and a person's age on that date to calculate their range of possible birth dates. | Click on the Date edit box arrow to view a calendar for the month. |
Date format (d-m-y or m-d-y etc.) will be copied from your Control Panel
settings.
Earliest date accepted by the date input field is Sep 1752; this
corresponds to the
change from the Julian to the Gregorian calendar with the skipping of 10 days.
Let the mouse cursor hover over the entry fields and buttons for help.
Note that for the 1841 UK census all ages 15 and above should have been
rounded down to the
nearest 5 year multiple, i.e. ages shown as 15 may be 15-19, ages shown as 20
may be 20-24, etc.
So when 1841 census is selected and the age is a multiple of 5 (15 or over)
a 5 year birth date range
is provided. (But entering this date manually in "Date of Event" gives
the normal 1 year range.)
