Friday night was buzzing with the excitement of hundreds of gay couples and thousands of well-wishers as the law changed at midnight, making same-sex weddings legal in England and Wales.
MONTH-BY-MONTH WEDDING PLANNER
The first of the weddings took place practically at the stroke of midnight when the law came into force, as hundreds of couples tried to claim the title of being the first to wed.
David Cameron famously said the reform was necessary because "when people's love is divided by law, it is that law that needs to change."
Writing in Pink News, the prime minister said: "This weekend is an important moment" because "we will at last have equal marriage in our country".
"The introduction of same-sex civil marriage says something about the sort of country we are. It clearly says 'you are equal' whether straight or gay."
The Marriage (Same-Sex Couples) Act came into force in July last year but it was not until 13 March this year when couples were able to register their intention to marry under the Act for the first time. A similar law passed in Scotland last month, with the first gay marriages due in October.
