* `Program_DateAdded` - our calculated field to understand when a page was added to a program.
* `Program_DateIncluded` - based on publish date of a dataset we identify when a page was included. This is just a date of publishing.
* `Added30days` - if a program was added within last 30 days.

1. If `Program_DateAdded` is `null` then we check previous day (i.e., `date - 1`, `day - 2` ...) and so on for previous ~30 days (or more? we think we can check for 365 days easily).
2. If `Program_DateAdded` is `null` for all previous days, we need to have fallback date which is `2019-09-25`
