[Feature] Customizable start date for shopify__calendar

[brian-equilife]

Is there an existing feature request for this?

• I have searched the existing issues

Describe the Feature

Currently the Shopify__calendar has a start date of 1/1/2019. I have orders and customers from 2018. Under the current structure customer_chort has customers showing 0 orders in month 1. To be in a given cohort you need to have at least 1 order in month 1 since that is what qualifies you. These customers had their first order in 2018 but their cohort_month 1 is calculated starting 1/1/2019. I've attached sample data to illustrate the scenario. I've removed the customer_id everything else is as created by the dbt package.

customer_cohorts_example_data.csv

Describe alternatives you've considered

I could clone the repository and modify it, but I'm just learning this stuff so I'd prefer a variable or earlier start data for the spine.

Are you interested in contributing this feature?

Hi there @brian-equilife thanks for taking the time to open this!

I think making this start_date customizable would definitely be beneficial to everyone using the package! IMO we should make a shopify__calendar_start_date variable, with the default value remaining 2019-01-01 so as to not to have a breaking change on our hands.

if that sounds good to you, the team can work on slotting this into an upcoming sprint

That sounds amazing. Thank you @fivetran-jamie
