Couples will be able to convert their civil partnerships into marriages for the first time today.
Ten same-sex couples will make history in Brighton later as they simultaneously convert their civil unions after Parliament approved a change to the law.
Ten registrars will take the couples through the process simultaneously in separate offices at Brighton Town Hall at 10am.
All 10 couples will be given a commemorative certificate to mark their involvement in the day's celebration.

A seagull caused a flap at Brighton racecourse when it become the first bird to feature in the photo-finish print for a horse race.
The bird was caught on camera "swooping for the line" at the end of a half-mile-race, flying in second behind Jewelled, ridden by Richard Hughes.
"We are about a mile-and-a-half from the sea, and there are a lot of seagulls around, but this has never happened before as far as we are aware," racecourse spokesman George Hill told the BBC.
"The bird just happened to be in the right place at the right time," he added.
After being buoyed by the latest polls, the Green party hope to get their best ever result in the European elections, but it is a different case in Brighton, where it has been anything but a smooth ride.
ITV News political correspondent Romilly Weeks reports:
The father of a British teenager killed in Syria says his son, Abdullah Deghayes, did "a brave thing" by going to fight against Bashar al-Assad's forces.
ITV News reporter Sejal Karia reports.
The father of a British teenager who died fighting in Syria has told ITV News he is "proud" that his son "sacrificed his own life for the sake of others".
Speaking from his home in Brighton, Abubaker Deghayes said his son was a "nice person" with many friends, although he was "a bit naughty, like any other teenager".
The father of a British teenager killed in Syria has described him as a "martyr" and tried to convince him not to fight in the war-torn country.
Abdullah Deghayes, 18, from Brighton, whose uncle is a former Guantanamo detainee, is believed to have died in April, after leaving the UK in January.
Mr Deghayes insisted his sons were not "terrorists" but travelled to Syria to defend "those who are weak" after seeing videos of the atrocities online.
His brothers Jafar, 16, and 20-year-old Amer also travelled to Syria. Speaking in Brighton, Mr Deghayes said:
As I far as I know Abdullah went to Syria without my consent, nor his mother's consent, to fight Syrians against the dictator Bashar al-Assad.
He was killed in a battle. His brother, who is also there, is injured. The third brother who is also there is OK. He is fine.
I never encouraged them, nor anybody, as far as I know. They went of their own free will. I hope he is in peace now.
Asked whether he believed Abdullah was a martyr, Mr Deghayes replied: "Of course I think, as a Muslim, that my son is a martyr. Anyone who dies for a just cause is a martyr."
The British teenager killed in Syria is the nephew of a former Guantanamo Bay detainee.
Abdullah Deghayes, 18, from Brighton, East Sussex, is the nephew of Omar, who was held in the United States as an enemy combatant at the detention centre between 2002 and 2007 after he was arrested in Pakistan.
The family of a British teenager who was killed in Syria said they had no idea he was in the war-torn country.
Abubaker Deghayes, the father of 18-year-old Abdullah, said he found out about his son's death on Facebook.
At the moment we do not have details of his death. All that we know is that he was killed in Syria. The family is mourning.
We are all in mourning. I'm trying to find out what's happened. At the moment we don't have any details. We found out on Facebook.
I hope he died for a noble cause, trying to help Syria. I need to find out. I might go and travel to see.
He was a youngster who didn't communicate a lot. With parents, once they grow, they don't tell you much about their lives.
