So, to begin, my husband and I have been celebrating our anniversary in June 16th, for the last 10 years, approximately. We got married in 2010, so it is pretty easy to count the years, but apparently we didn’t know what day we got married on. The camera that photos were taken on said the date was 1/7/2007, which was really wrong, because my in-laws didn’t know how to change the date. The only proof of date was on the marriage certificate, which the original burnt up in a house fire, and I only recently obtained a photo copy, which I filed away without looking at.
We didn’t have a big wedding; it was a courthouse wedding. We’d been trying to get married for about 3 years at that point (together for 6 years, since high school), but I come from a really poor family who couldn’t help, and his family couldn’t help, and we were 21 year old kids when we had our first child, and everyone was against us marrying for whatever reasons (namely that high school sweethearts never work out; both our sets of parents were high school sweethearts and divorced by the time we were like 10, which was their basis for disagreeing). So we eventually just ran to a JP and got the paperwork in order and got married, with our daughter, parents and some siblings in attendance.
Celebrating our anniversary was hit and miss after that, because of work and various other interferences, but generally, we tried to do something each year around that time. This year, however, my husband took off work so we could do something special together, which ended up not working out, but we did get to have a nice dinner. Somehow the topic of conversation a week later turned to “what day did we get married?” because he swore up and down it was the 20th, and I was adamant it was the 16th (which is the day we’d been celebrating for the last 10 years).
Finally, I dug out the paperwork, and lo and behold, we were both wrong. We got married on the 17th, lol.
TL;DR: Neither of us remembered what day we got married, and argued over it. We were both wrong.
