One thing is for sure, whether you are a fan of the royal family or not, the whole world is going to be going nuts this Saturday as Prince Harry weds Meghan Markle.

Ever since the couple announced their engagement news back in November, there has been a global obsession with everything royal wedding related, from all kinds of merchandise being made to an in depth analysis of every final detail of their big day.

If you too can't help but be fascinated with it all, here's everything we know so far about the most anticipated wedding of the year.

When?: 12 noon. Saturday, May 19, 2018.

Where?: St. George's Chapel at Windsor Castle, while there will be a carriage procession at 1pm around Windsor Town.

The reception is at St George's Hall but there will be a second evening reception later at Frogmore House where The Prince of Wales will host a private evening for the couple and their close friends and family.

How can I watch it?: The wedding will be shown in Ireland on RTÉ One with Maura Derrane, Evelyn O'Rourke and Darren Kennedy presenting live coverage from St George's Chapel from 11.30am.

You can also watch it at 12pm on TV3 where Julie Etchingham and Phillip Schofield present coverage while you can also see them on 3e from 9.25am.

Coverage will begin on BBC One at 9am where Kirsty Young, Huw Edwards and Dermot O'Leary will be presenting.

Finally, you can watch the wedding on Sky One also where Kay Burley, Anna Botting, Jayne Secker, Sarah-Jane Mee, Colin Brazier and Jonathan Samuels present live coverage from 9am.

In summary, there's not much escaping it.

Who will walk Meghan down the aisle?: It was supposed to be her father, Thomas Markle, but following a controversy surrounding some staged paparazzi pics, he now will not be attending. Her father also suffered a heart attack recently but he had still planned to attend the wedding prior to the scandal unfolding.

Kensington Palace have said in a statement that: "This is a deeply personal moment for Ms Markle in the days before her wedding. She and Prince Harry ask again for understanding and respect to be extended to Mr Markle in this difficult situation."

*Update: Meghan Markle has also released a statement. 

What about the all-important dress?: This is one of the most tightly kept secrets of the entire wedding and we won't know for sure until the bride first makes her appearance on Saturday.

Who is the Best Man?: Harry's bro William of course.

Who is Meghan's Maid of Honour?: She won't be having one. Perhaps wise considering how much the world obsessed over Kate's sister Pippa after that wedding. Meghan has said she will be assisted by good friends on the day however.

Will there be Page Boys and Flower Girls?: Yes there will be. They will of course include Prince George and Princess Charlotte - you can read about who the rest of the little ones are here. 

Will there be a balcony pic a la Will and Kate?: Palace officials have confirmed that there will not be. No reason is known but it's likely a distance issue.

Who will perform?: The music will be under the direction of James Vivian, Director of Music, St George’s Chapel,  and will includie the Choir of St George's Chapel, and a selection of choral groups, soloists, and musicians including 19-year-old cellist Sheku Kanneh-Mason, winner of 2016 BBC Young Musician Award.

Who is invited?: The main guest list has been kept under wraps but 3,000 general members of the Commonwealth have been invited to the nuptials and it looks like a few of Meghan's Suits co-stars will be showing up too.

Visitors to Windsor on the big day are being encouraged to gather on the Long Walk — the final stretch of the procession route — where big screens and food stalls will be available.

Can I send a gift?: Yes, you can actually but the couple have requested that all gifts be a donation to one of seven charities they chose themselves. Details of which you can find here.

Who is planning the wedding?: Mostly the couple themselves but it's thought that Markle's best friend and personal stylist, Jessica Mulroney, is helping out too.

Who will give the wedding sermon?: The Most Reverend Michael Bruce Curry, the twenty-seventh presiding bishop and primate of the Episcopal Church.

Who is making the wedding cake?: Acclaimed baker Claire Ptak is set to be making a lemon elderflower cake that will be covered in buttercream. Yum.

Who is doing the flowers?: The woman known as the "Queen of London Florists", Philippa Craddock.

Who is the photographer?: Renowned fashion and portrait photographer Alexi Lubomirski will take the official photographs of the newlyweds at Windsor Castle after the ceremony. He previously took their photos at Frogmore House in the weeks after they announced their engagement.

What's the plan for the couple the night before: Harry and Meghan will follow tradition and spend the night apart. It's thought that Prince Harry might spend time with Prince William and go for a walk around Windsor Castle that evening to greet the well-wishers waiting outside while Markle will most likely stay with her mother that night.

Will they be heading on honeymoon?: Not at first. It will be business as usual for the couple the following week but it's thought they will head away at a later date.
