My events are 1 hour off!
Time differences are always caused by calendar using different timezones: this can cause your events to be one or more hours off, for example.
The solution is to ensure both apps use the same timezone.

Ensure the iPhone's calendar and Week Calendar are using the same timezone:
- A. Please check the default calendar apps TimeZone support at System Settings > Email, Contacts, Calendars > Timezone Support.
- B. Ensure that Week Calendar uses the same settings. To do so, please do the following:
- tap on the little gear icon in the bottom bar (1st icon next to the today button)
- in the upper-left corner, tap on "Settings"
- go into the "Calendar" entry
- Make sure that under "TimeZone Support" the same settings are used as you found at step A.
If this fails:
Please remove your synced iCal calendars from your iPhone, wait 5 minutes and re-add them again. This usually clears the timezone cache of your iCal calendars.
