This app works so good! I use it for my business to remember anniversary dates of contracts (annuities, etc.) and also dates when spouses die so I can send a card in the future. There are so many uses and it does work flawless! This app brings Address Book to a truly useful and professional level. I recently upgraded to Lion and also iCloud, and when I had an issue, I was emailed the solution within 5 minutes and it was right back to normal. This program is worth it's weigh in GOLD. It is sincerely one of the best apps I have ever downloaded. Don't hesitate to purchase!!! 10 out of 10!!!!I It also works on putting the dates on my macbook air, and 2nd iMac and also iPhone.

It is still crashing for me. Running a 17" G4 PPC mac 10.5.8. all software less itunes up-to-date. Author did provide a one off fix which I tested and it worked. Have returned to that one off fix. Since that works, believe author will resolve this issue also. Sent in crash reports and the results of my t/s to date. Author responsive.

The App works great. Tried it with iCal and Busy Cal's beta. It will solve my dupe problems on my home network.

This is an app that fill in on one of Apples many omissions in their own applications. iCal 2 has an automatic birthday calendar feature that syncs with AddressBook, but for some reason Apple has omitted the ability to sync custom dates, and to set alarms for the events.
DatesToiCal solves the issue nicely, and utilize OSX technology to make your calendar update automatically if you make any changes in AddressBook.
Another aspect that makes this app deserve honourable mention is the support from the developer. Initially I couldn’t make DatesToiCal work. I contacted the developer, and got a very quick response, and he was truly interested in solving the problem. As it turned out, the problem was another application to blame (the offending app hasn’t been updated for years). This commitment to customer service actually made me do my first ever contribution to donation ware.
I can only give my best recommendations.

This is a very good program, I have been using it for months now. It is unobtrusive and just does it's thing in the background. Rememebering birthdays have been error free all year! It's so easy that I forgot all about it--until I installed MarkSpace's Missing Sync for Pocket PCs. Then all hell broke loose. Some how Missing Sync Broke Dates to iCal's run script. The script tries to run ever minute or so, with no luck, resulting in a very annoying error message box that won't go away. So keep that in mind if you are a Missing Sync user.
