WHEN IT HITS THE FAN**: YOU FORGOT HER BIRTHDAY**.
Apologizing profusely. That’s option number one. Some say, it’s the only option.
Then I heard this suggestion: “Tell her, that you knew her birthday was on Thursday but that you wanted to take her out on Saturday."
Any other options/suggestions?
You ordered her a present on eBay or Amazon and it’s taking longer for it to arrive than it was supposed to.
Or just go with, “You’re a timeless treasure. I thought you stopped having birthdays. You look younger every time I see you.”
Under no circumstances apologize profusely. If you do, you might as well cut off your balls.
Treat women as rational, intelligent, mature human beings and expect them to act that way. If they don’t act that way, they’re not worth the bother.

No idea, I’ve been using smart phones for so long that I get automatic reminders of important dates well in advance. Hell even my yahoo email account has the birthdays of everyone I know marked on the calendar with reminders up to two weeks in advance.
I suppose if I was caught in the situation I’d shift it slightly. I remembered/knew when her birthday was…I just lost track of todays date. “You mean it’s friday already? holy crap I spent the whole time thinking it was barely wednesday!”
But seriously, you can set up the calendar in yahoo mail with the birthdays and holidays you need to remember and even set it to send automatic reminders at intervals ranging from two weeks to three days in advance…both by email and by text message. So there’s not a whole lot of excuses.
Apologize the fact that you lost track of time. You didn’t forget the actual day.
You guys are funny…
That actually happened to me once, a looooooong time ago… I was “seeing” this guy and he forgot my birthday and I’m certainly not the type to do “a countdown” to the day, so I didn’t remind him or anyone else. *Side-note: I’ve told him several times in the past when he asked me when my birthday was, so it’s not like it was news to him & he didn’t have to remind me about his birthday, which came before mine.]
So, my birthday came and I had a great day; because he didn’t remember what day it was, we didn’t arrange to meet (it fell on a Wednesday)… So we’re on the phone, as I’m getting ready to go out w/the fam and he asked something like “why are going out on a Wednesday?” So I told him my parents were taking me to diner for my b-day.. Can you imagine he got MAD at me, because I didn’t tell him it was my birthday??? 
Needless to say, we’re NOT together! 
I’ve seen this one gets big kudos: send a **handwritten note and flowers to her workplace (that’s important) so her friends notice.
Simple, get a GF who’s birthday is the day before or the day after yours.
(In my case she’s the day after.
)
Purchase a few big sticks of sidewalk chart (your choice of colors) and write a short and sweet note in front of her house - so that she will see it. Remember it has to be short sweet.
