Marry when June roses blow, over land and sea you'll go.
They who in July do wed, must labor always for their bread.
Similarly, it became unusual for a couple to be wed in May as this was the traditional start of Summer and was marked by a Pagan feast: Bealtane.
These beliefs are the origin of the old marriage song:       Marry when the year is new, always loving, kind, and true.
This made sense as it was the day when the working week was done and people were free to attend the simple marriage ceremonies that were available at the time.
As the decades and years rolled by and as the Catholic religion developed and reasserted itself in Ireland, the choice of Sunday became frowned upon as it was often seen as a mark of disrespect.
Or at the very least you can add some lovely traditions and Irish Wedding Customs from the Gaelic history of Ireland to your big day. It is not unheard of for hundreds of guests to attend a fancy hotel for a swanky reception, for children in formal attire to be employed as page boys, ring bearers and even seating attendants!
If you wed when March winds blow, joy and sorrow both you'll know.
Marry in April when you can, joy for maiden and for man.
Marry in the month of May, you will surely rue the day.
Whoever wed in August be, many a change are sure to see.
The 16th Century Penal Laws prevented Priests from saying Mass never mind conducting the Sacrament of Marriage. The last of the Penal Laws was not repealed in Ireland until 1920.Given this background and the unique identity of the native Irish people who were forced to practice their religion 'underground', it is not surprising that an Irish Wedding has a particular identity all of its own and has a number of specific traditions associated with it. In Ireland of centuries ago the most popular day to be married was a Sunday.
