Holidays table is older than HolidaysRules table
Cause : Changes were made to the shared holidays rules database, since you last generated holidays on your PC. However, as far as Q++ can tell, these changes do not affect any of the Holidays Sets used in the current script (if they were, you would get another message).
Consequences : Unless you are using a very twisted Macro, Q++ will have correctly guessed that the modified holidays rules do not apply to the current script, and you can safely generate a diary without re-generating holidays. We suggest, however, that you re-generate holidays at the earliest convenient time (when you go for coffee, for example) so that you do not have to wait when you do need an updated holidays list.
•Re-generate Holidays : selecting this option will automatically regenerate the list of holidays occurences.
