Jahresunterschied herausfinden

Mit folgender Formel finden wir den Jahresunterschied heraus:

sub(int(formatDateTime(body('Aktuelle_Zeit'), 'yyyy')), int(formatDateTime(outputs('Projektinfos_abrufen')?['body/Vertragsbeginn'], 'yyyy')))

Calculate delta of months

sub(int(formatDateTime(body('Aktuelle_Zeit'), 'MM')), int(formatDateTime(outputs('Projektinfos_abrufen')?['body/Vertragsbeginn'], 'MM')))

Combining the year difference and the months

add(mul(outputs('Delta_der_Jahre'), 12), outputs('Delta_der_Monate'))
