Contact Birthdays Not Showing In Calendar

[Taz Man]

ok guys, finally found out what was wrong!
First I want to make sure we are all on the same page here:
1. When inserting a birthday on a contact, you can see the entry in Google Calendar (https://www.google.com/calendar/render) but you cannot see the entry on S Planner!
2. The entry exists on contact level both in the contacts of the device and in the contacts of GMail Contacts
IF this is the case then the solution to the problem is the following:
Go to System Settings --> Application Manager -->ALL
Find Application "Calendar Storage"
Open it and Clear Data
Open S-Planner and Re-sync your Calendar (Menu --> Sync)
All birthdays should appear correctly now

I realized that the calendar either gets a max value and does not update or there must be a kind of bug in there cause, the entry is there (since opening Google Calendar online you can see the entry) and after deleting and re-creating the contact does not fix the problem.

Please post back results

The issue with most of this is that almost all of the solutions people have given all require that you have your contacts saved to Google, if you do not then it doesn't work.
The aCalendar app does use the phone contacts instead of the google ones.

I had the same problem, the birthday from some contacts did not appear in Google calendar. I have checked all the boxes to show them in calendar, I have sync and check all the boxes from the Google account and nothing.
I have noticed that the specific contacts had been merged with WhatsApp number, after the unmerged or split them to only be one contact with the sim number and also did a refresh in Google calendar app, the birthday appeared for that contact.

My phone was doing that the other day as well. I tried doing a sync multiple times and nothing. However, the next day, I checked my calendar and the birthdays appeared. Strange.. the birthday stuff is quirky for some reason.
