Pius IX defined the Immaculate Conception in 1854: Mary was kept free from original sin from her conception. The novena runs November 29 to December 7.

The United States
On December 8, 1854, Pope Pius IX defined in the bull Ineffabilis Deus that Mary was preserved from original sin from the first moment of her conception. The feast had been kept for centuries before that. The Raccolta of 1910 gives a different prayer for each of the nine days, each one naming Mary with an image of purity: lily, rose, mirror, moon, star, morning, sun and light.
The Immaculate Conception is the patronal feast of the United States, chosen by the U.S. bishops in 1846.
It is about Mary's own conception, not the conception of Jesus.
Four years after the 1854 definition, Bernadette at Lourdes reported the Lady saying 'I am the Immaculate Conception.'
A novena is nine days of prayer for one intention, modeled on the nine days the apostles and Mary prayed between the Ascension and Pentecost (Acts 1–2). Pray this each day:
Day 1. Behold me at thy sacred feet, O Immaculate Virgin. I rejoice with thee, because from all eternity thou wast elected to be the Mother of the Eternal Word, and wast preserved stainless from the taint of original sin. I praise and bless the Most Holy Trinity, who poured out upon thy soul in thy Conception the treasure of that privilege. I humbly pray thee to obtain for me grace effectually to overcome the sad effects produced in my soul by original sin; make me wholly victorious over them, that I may never cease to love my God.
Day 2. Mary, unsullied lily of purity, I rejoice with thee, because from the first moment of thy Conception thou wast filled with grace, and hadst given unto thee the perfect use of reason. I thank and adore the ever blessed Trinity, who gave thee those high gifts. Behold me at thy feet overwhelmed with shame to see myself so poor in grace. O Thou who wast filled full of heavenly grace, grant me a portion of that same grace, and make me a partaker in the treasures of thy Immaculate Conception.
Day 3. Mary, mystic rose of purity, I rejoice with thee at the glorious triumph thou didst gain over the serpent by thy Immaculate Conception, in that thou wast conceived without original sin. I thank and praise with my whole heart the ever blessed Trinity, who granted thee that glorious privilege; and I pray thee to obtain for me courage to overcome every snare of the great enemy, and never to stain my soul with mortal sin. Be thou always mine aid, and enable me with thy protection to obtain the victory over all the enemies of man's eternal welfare.
Day 4. Mary Immaculate Virgin, mirror of holy purity, I rejoice exceedingly to see how from thy Immaculate Conception there were infused into thy soul the most sublime and perfect virtues with all the gifts of the most Holy Spirit. I thank and praise the ever blessed Trinity who bestowed upon thee these high privileges, and I beseech thee, gracious Mother, obtain for me grace to practise every Christian virtue, and so to become worthy to receive the gifts and graces of the Holy Ghost.
Day 5. Mary, bright moon of purity, I congratulate thee in that the mystery of thy Immaculate Conception was the beginning of salvation to the human race, and was the joy of the whole world. I thank and bless the ever blessed Trinity who did so magnify and glorify thy person. I entreat thee to obtain for me grace so to profit by the death and passion of thy dear Son, that his Precious Blood may not have been shed upon the Cross for me in vain, but that after a holy life I may be saved.
Day 6. Mary Immaculate, brilliant star of purity, I rejoice with thee, because thy Immaculate Conception brought exceeding joy to all the angels of Paradise. I thank and bless the ever blessed Trinity, who enriched thee with this privilege. Enable me also one day to take part in this heavenly joy, praising and blessing thee in the company of angels, world without end. Amen.
Day 7. Mary Immaculate, rising morn of purity, I rejoice with thee, and I am filled with admiration at beholding thee confirmed in grace and rendered sinless from the first moment of thy Conception. I thank and praise the ever blessed Trinity, who elected thee alone from all mankind for this special privilege. Holiest Virgin, obtain for me so entire and lasting a hatred of sin, the worst of all evils, that I may rather die than ever again commit a mortal sin.
Day 8. Mary, Virgin, sun without stain, I congratulate thee and I rejoice with thee, because God gave thee in thy Conception a greater and more abundant grace than He gave to all his angels and his saints together, even when their merits were most exalted. I thank and admire the immense beneficence of the ever blessed Trinity, who hath dispensed to thee alone this privilege. Oh, enable me too to correspond with the grace of God, and never more to receive it in vain; change my heart, and help me to begin in earnest a new life.
Day 9. Immaculate Mary, living light of holiness, model of purity, Virgin and Mother, as soon as thou wast conceived, thou didst profoundly adore thy God, giving him thanks, because by means of thee the ancient curse was blotted out, and blessing was again come upon the sinful sons of Adam. Let this blessing kindle in my heart love towards God; and do thou inflame my heart still more and more, that I may ever love Him constantly on earth, and afterwards eternally enjoy Him in heaven, there to thank and praise Him more and more fervently for all the wondrous privileges conferred on thee, and to rejoice with thee for thy high crown of glory.
