Our goal is to understand users' engagement in the first 14 days since sign up (see day per day event usage) through a stickiness chart. We were trying to use a derived property to calculate this date range based on today's date and user's sign up date but we haven't been successful. Any idea on how we can achieve this? Thanks!

Hi @Esha 

They have a formula documented for calculating a user’s age in here. You could try applying a similar logic using a user’s sign up date.

Thanks @Saish Redkar! Always a wealth of knowledge. 😊

Hey @Esha, definitely try that out and these steps below might also help:

  1. The account creation date can be sent as a user property. Looking at your project, I can see that you are using our iOS SDK and Android SDK. You can take a look at our documentation below for user property setup.

 

2. The account creation date can be formatted as an Epoch value or a string (YYYY-MM-DD HH:MM:SS). To segment users by the account creation date, you might want to apply operators: "greater or equal", "less or equal", "less" or "greater". For example, account_creation_date is greater than "2022-03-01".
 

Our Demo has a similar user property which is "trial_start_time".

Hey @Esther Trapadoux , thanks so much for your help! Our dates were definitely wrong; we were sending them as utc string instead of an iso string!

@Esha date time formats are the bane of my existence. 😖
