Re: my calender keep

@Emja01 from the screenshot I can see that you use a 7 day season. That means that you will use 28 days in a year. But when you use a long life span for your Sims ageing a Sim can vary form 32 days for a toddler to 94 days for an adult or young adult. This means that adults and young adults will only have a birthday once in the 3 or 4 years. Children will have a birthday once in the two years. 

As soon as you make the life span shorter to normal the frequentie of birthdays will come in range of the seasonal gameplay. Only when you use a short life span your sims will be able to celebrate more birthdays.

As a warning the gameoptions for the seasons state that changing the duration of the season will also alter the position on the calendar and the events that might occur during a season. So please check out these settings. So please keep this in mind when setting the options for Sim life span and seasonal length.

Have fun playing. 😉
