I believe it is the same song as Peter Paul and Mary's Monday Morning from their 1965 recording "A song will rise". The discogs entry for the single gives arranger rather than composer credits for the song to P P and M and their musical directory Milton Okun.
Arranged By, Adapted By – Travers, Okun, Stookey, Yarrow
, so I guess it is a traditional folk song.
Other (folk music) sources mention the song with different words and different names: which is kind of what happens with folk music. There looks to be more information in a scanned online copy of the "Journal of Folk Song", 1905, Number 6 Volume 2
where the song is referred to as "At the sign of the Bonny Blue Bell".
The words are a bit different, but the first lines, apart from the day, are pretty much alike :
"As I was a - walking one morning in the spring,
To hear the birds whistle and the nightingale sing
I heard a fair damsel so sweetly sung she,
Saying, "I will be married on a Tuesday morning."
the article mentions some other songs with similar tunes or themes, but also says :
The whole ballad, under the heading " I shall be married on Monday
morning," is printed on a broadside by Williamson, Newcastle, circa
1850. This may be a version of the 17th or 18th century original.
Part of it runs :
" As I was a- walking one morning in Spring
I heard a fair maiden most charmingly sing,
All under her cow as she sat milking,
Saying 'I shall be married next Monday morning.' "
