Iphone iOS 4 Contact Birthday Date Bug.

Just gonna add to the big list of 'same heres'...

yep i'm experiencing the same issue, using iOS 4.1, phone displays wrong birthday when selected from the date wheel... (same with anniversaries) So it makes my Microsoft exchange contact sync, sync the incorrect birthdays...

yay... Not.

yay someone else experiencing the same issue...

I have the same issue; iPhone 4 on iOS 4.1 syncing with Exchange 2007.

Exchange/Outlook/OWA show the correct birthday in both contacts and calendar. iPhone shows the correct birthday in the calendar. But not in contacts.

My time is set to update automatically from the network, and I'm in San Francisco. My Exchange account has time zone support turned on and set to San Francisco.

Why is the iPhone contacts list the only place where the birthday is one day off if it's correct everywhere else? And this has been an issue for years; how can this not be fixed yet?

I have the same problem, have been looking for solutions for this for a long time, but it seems no one cares to fix it? iPhone 3GS with latest iOS 4. Time zone GMT+1

I have the same problem. First I thought it could be because sinc. between iphone/ipad and gmail, so I was searching for a solution @ google. Now I changed from gmail to outlook and when sinc. the same problem occures. iphone/ipad +1 day , sometimes +5 days....When das apple solve this problem ?

Same problem here.
If you look I think you will find the blue dot will be an event put directly into the calendar.
The red dots are generated from the dates in your contacts. I have been doing a lot of reading on this and it seems to be something to do with timezones.
Come on Apple. Fix the problem please.

Has anyone tried a different address book or contacts app that doesn't use the one built into iPhone.

This bug existed way before iOS4. I raised an issue back in 2009 and exchanged numerous emails with Apple support. They concluded that it was corrupted data imported from a previous device. The conclusion was for me to delete my address book and re-enter all my data from scratch.

I finally went through this process and can now firmly conclude that this is an Apple problem. In my case the sync between my MacBook Pro and iPhone (3GS with iOS4) using a USB connection causes birthdays to shift days from that set. Syncing between my MBP and iMac using MobileMe does not cause this problem, however if I try to sync the iPhone using MobileMe things go all over the place.

Apple this is a bug, it has been around for more than a year and it is SERIOUS. I like several others will look at alternative devices if this is not fixed and will advocate strongly to others to do the same - simply put the device is UNFIT for purpose.

Yeap, I'm another with this problem, April 30th and other dates all show a day later, have tried changing in Outlook, setting Time Zone, all are correct... Apple needs to fix this, 1 more reason I'm looking at changing phone types, sick of things like this being incorrect. 4.2.1 doesn't fix it.

I have the same problem, and find it very frustrating.

A birthday in my GMail contact is say the 1 Dec but shows up on my iPhone a day later the 2 Dec.

But it appears correctly in the Calendar app, weird hey, that tells me there is something wrong in the Contacts app.

I logged a bug with Apple and they are looking into it. It would be a good idea for everyone who uses the birthdays and are experiencing this bug to submit feedback http://www.apple.com/feedback/iphone.html

I would like to see this fixed, it also messes with apps that use your birthday like Occasions

Same Problem here.

APPLE DOESN'T CARE!
THIS CAN'T BE TOO HARD TO FIX!

Ok, tested a lot. this is ridic... and its obvs a time zone problem.
when i enter a new contact on iphone with birthdayfield 07/01/2011 it syncs and outlook shows the birthday field as 08/01/2011.

so i wondered if it could be a "day time" savings error, so i just set my time zone on the PC to Azores (and also got the time correct), and kept timezone on iphone as Lisbon. Created a new contact on iphone with same birthday as above and it show on outlook just the same. so i thought i had it! but then i created a contact with a birthday on July (like 7/7/2010 so it would be a summer date) on iphone again and fck me... it showed on outlook 8/8/2010).
Even when editing (and this is the worst)a existing contact (like getting a surname an the contact, or a new phone number), after sync the birthday will move up one day later on outlook...TRY it and mess up your address book.

For last, i can only complain to mobile network (Vodafone in my case); it could be possible for the network to be "feeding" the date/time for the iphone in Summertime settings (one hour ahead), so, when i enter 07/01/2011 for a birthday it goes from 00:00 to 23:59 (or 00:00), but when iphone syncs with outlook, and outlook is obviously in winter time, outlook "reads" it from the iphone as from 01:00 to 01:00 of the next day, making it move the birthday on outlook one day forward. I mean, if i'm born at midnigh of the 7th, if iphone time is fed from network as summertime, this same midnigh will mean 1 o'clock in the morning. so my birthday "will go" from 1 to 1 and not from 00 to 00. when it syncs back to outllok, outlook may know my iphone time, but not if it is in "summertime" mode, so it reads my birthdy as starting at 1 o'clock, thus ending the next day, moving the date forwar because of this.
fck, i'm messed up!

Just got my new iPod Touch 4 and having this issues.

On iOS 4.2 but still doing it. I found a workable solution for me though. It seems that (on my touch anyway) the error only occurs from dates past 1933 so I just put my birthdays back a century. So April 2 1983 comes up as April 3 1983 but by changing the year to 1883 it shows April 2.

this has been an issue since mid 2008 at least!! - however back then not many people had iphones in NZ and I couldn't find much info on it. A work-around to this issue is to move to another time zone 😉 I had completely forgot about this problem until a recent visit back in NZ I noticed several contact birthdays had jumped forward a day after setting my phone to the NZ timezone.

Absolutely astounding that several years, phones and major iOS versions later this still isn't fixed. So don't hold your breath for a fix to this one. Bet it would be fixed by now if it affected US users!

Booo Apple! this issue will be 3 years old soon... give or take a day ;-p

I have this problem on 2 iPod touch (first model and one only 3 weeks old), an iPhone 3GS and an iPad. All running on latest iOS. And guess what??? I live in NZ!!!

Wake up Apple and get it right, how hard can it be?? Microsoft seem to have it together with Outlook, is it too hard for the Apple geeks??? Get your heads out of the clouds (pun intended) and focus on the real issues.
