I think Ireland and UK are outliers with the dates. I bought flowers to an Asian lady friend who was wondering what they were for. When I told her she laughed and said it was 12th May . When in Rome I thought to myself but she was happy enough 😁.

The most important woman for most Irishmen is their mammy. Mines passed away also but even when I worked outside Ireland for a good few years flowers and a phone call were essential on the day. I wouldn’t think that’s unusual either .
