Google Daterange Operator

It is possible to get Google to search for pages that were indexed within a certain range of dates. It is a bit clunky but quite useful. The syntax used is the Google daterange: operator and the parameters are a pair of dates separated by a dash. So far so good … The downside is that Google needs the dates to be formatted as Julian dates, ie: The number of days that have passed since January 1st 4713BC (on the Julian Calendar).

In addition Google does not officially support the daterange operator, so potentially it could be withdrawn at any time.

For conversion between our date format and Julian dates, see here:
