Famous quotes containing the word calendars:

    Tomorrow in the offices the year on the stamps will be altered;
    Tomorrow new diaries consulted, new calendars stand;
    With such small adjustments life will again move forward
    Implicating us all; and the voice of the living be heard:
    “It is to us that you should turn your straying attention;
    Us who need you, and are affected by your fortune;
    Us you should love and to whom you should give your word.”
    Philip Larkin (1922–1986)
