Slides of some talks delivered by Dimiter Skordev

“Can every day be Easter?” (in Bulgarian, PDF, 270 Kb) – slides of a talk given on June 9, 2011 in Sofia. Each day of the year is shown to be the Gregorian date of the orthodox Easter under the present rules at least once in the period from the year 2012 till the year 46455 inclusive (the statement can be strengthened by replacement of 2012 with 2447).
Remark. Unfortunately, as observed in December 2014, the second of the Internet pages indicated on the slide before the last no longer exists.
