AS the whole world lit up in 40 million shades of green, St Patrick's Day at home got underway with a traditional swing.
On a day when Google marked the occasion with little green Irish dancer "cailini", every town and village in the country came alive to celebrate our national day.
And despite snow, sleet, rain and even a brief spell of sunshine, thousands came out to line the streets for the parades.
Spirits were high for the special People's Parade which kicked off the day in Dublin, as part of the Gathering.
Around 6,000 participants from 144 countries worldwide samba-ed, flamencoed, folk-danced or just plain marched the route from Parnell Square just past St Patrick's Cathedral before the main parade began at noon, led by Grand Marshall Nicky Byrne.
Half a million people turned out on the streets of the capital - though figures were said to be down because of the exceptionally cold weather.
The largest ever group of representatives of the gay, lesbian, bisexual and transgender community took part in the parade from "Dublin Pride and BeLonGTo", marching with the City Fusion pageant group.
The national party started at dawn with a 6am parade through the streets of Dingle by the Dingle Fife and Drum band - a tradition since the Land War of the 1870s.
In Cork the Grand Marshall was San Francisco Lord Mayor Edwin Lee, with over 80,000 people out watching.
In Galway, up to 60,000 people attended the city centre parade appropriately featuring Tribes and Tribesmen, with any international visitors bearing the surname of one of the 14 tribes of Galway invited to march, in a Gathering initiative.
While in Limerick, 4,000 people took part in a parade led by a 14 foot high St Patrick with the theme being Saints and Scholars, as the city celebrated its unique history.
