There are many gay couples who have been eagerly awaiting this news and will now be able to plan their wedding. The first marriages will, I hope, herald a new age of equality in our country, where all couples, regardless of their sexuality will be treated equally under the law, and eventually in society.
We now await news on whether the Government will equalise private pension rights for same-sex couples and publish the process for gay couples to convert from civil partnerships to marriages.
After announcing that gay couples will no longer have to wait until July 2014 to tie the knot, equalities minister Maria Miller called the Marriage (Same-Sex Couples) Act "another step in the evolution of marriage."
The date of the act was moved forward today from July to March 29 2014. Couples wishing to be among the first to marry will need formally to give notice of their intention to marry on March 13.
Ms Miller said: "Marriage is one of our most important institutions, and from March 29, 2014 it will be open to everyone, irrespective of whether they fall in love with someone of the same sex or opposite sex.
"This is just another step in the evolution of marriage and I know that many couples up and down the country will be hugely excited that they can now plan for their big day and demonstrate their love and commitment to each other by getting married."

Gay marriage has become legal in Britain after the bill was granted Royal Assent by the Queen.
Legislation to introduce same-sex marriage is expected to complete its passage through the House of Commons today, paving the way for the first gay weddings in England and Wales next summer.
Jubilant gay rights campaigners were last night celebrating the succesful passage of the Marriage (Same Sex Couples) Bill through the House of Lords - and vowing to take the fight for marriage equality to Scotland and Northern Ireland.
MPs will this evening debate amendments made to the legislation in the Upper House, but this is expected to be little more than a formality and is unlikely to delay its progress into law, with Royal Assent within the next few days.
The Labour Party has published a video message from leader Ed Miliband in support of the London Pride parade.
"It promised to be a very, very important year if we can get the same-sex marriage bill passed," said Miliband.
"I'm proud to support that bill because I believe that the gender of the person you love shouldn't determine whether you can marry them."
