As Easter is celebrated throughout the Christian world, we at IBTimes UK wondered what the world's most prominent atheists get up to when they've got nothing to celebrate.

Here's what we discovered.

Richard Dawkins
Having solved to his own satisfaction the big question, Does God Exist? (Answer: No) Richard Dawkins continues to apply his ferocious intellect to the matters at hand.

For fans, here's a bit of vintage Dawkins on YouTube.

Stephen Fry
Fry has been busy this Easter, promoting a new video he's made for the British Humanist Association with a rare interview.

"Most people in Britain aren't religious," he says, "and we wanted to let people know that there is a positive word for what they believe: Humanism. Younger people in Britain are generally not as religious as people from older generations—but as with anyone else it's not always the case that it's easier for young people who are questioning the world around them to encounter the full range of options available to them. That's why it's important for have campaigns like these, to reach new people."

And here's the video in question.

Bill Maher
After the tirade against the film Noah, below, we think American comedian Maher is probably having a lie-down.

Billy Connolly
All quiet today, but has made his views on organised religion very clear.

Tim Minchin
The Australian comic singer and actor cheers fans up with a link to a classic performance.

Kathy Griffin
She enraged the religious right in 2007 with the Emmy acceptance speech below, but today it's all about the food.

Nigella Lawson
She once told the Times: ""I was brought up an atheist and have always remained so. But at no time was I led to believe that morality was unimportant or that good and bad did not exist. I believe passionately in the need to distinguish between right and wrong and am somewhat confounded by being told I need God, Jesus or a clergyman to help me to do so."

Unsurprisingly, her definition of Easter revolves around food.

Mira Sorvino
In 2007, Sorvino told GQ: "When you are a Christian, your law is laid out for you in codified form. You can have some kind of debate about this or that, but basically you're supposed to accept God's will. There is no argument about whether there is a definitive right and wrong. And once you know this law, nobody else can be right unless they agree with you. And so you wind up with, 'You are wrong. You are mistaken. You are sinning. You are in error.' I find that extremely restrictive and impossible."

In 2014, Sorvino appears to have spent some of last week in the pope's back garden.
