Are you really 18 years old today?
18 is a nice age here. You can vote, you can watch movie or drink Gin-tonic. You also get married and go to jail !

By the way, do you know “The Pirates of Penzance”? The whole plot turns around the hero who was indentured to pirates until his 21st birthday. BUT he was born Feb 29. No one ever claimed that Gilbert and Sullivan make sense.

Hi Claudia,
No, I did not know the Pirates of Penzance.
I have an uncle who is celebrating his 18th birthday tomorrow… since his father reached its 101st I would not be surprised he will reach 21st.

nothing unexpected..
doc:
If date is the last day of the month or if the resulting month has fewer days than the day component of date, then the result is the last day of the resulting month.
nothing unexpected if you read the doc before using add_months
If I was born Feb 28, 1990. Today is my birth day for 18 years old.

OK!
I can watch adult movie or drink Gin-tonic.
create function add_mon (date1 IN DATE,add_mon IN NUMBER) return DATE IS loc_date2 date;

not sure if you can enter the party when born 29-FEB-1991 next year before 1st march… depends on the bodyguard
of course my comment is not very accurate… I mean if you are born 29-feb-1992 you will not be 18 on feb-28-2010 but one day later
common law provides that a person becomes 18 at 12:01 am on the day before the 18th birthday.
which law? which country?
any link to any government-hosted website?
hi, i was born feb. 29 1992 and i’ll be turning 18 soon but the problem is when? will it be feb.28th because its the last day of that month or will it be march 1st? i’ve always held it on the 28th every common year beacuse i have twin brothers born 2 years before me on march 7th, so i can have my own month. i need to know governmently wise when will i be 18 but i just cant find my answer!!!!
it depends on the country. In France, you would be able to vote or get elected on Feb 28.
Did you intend to drink alcohol on that day? Get married? Commit crime? (or all three)
Please try to look in your government websites
