Improve Date Picker

[leonieherma1]

Summary
As a DHO user I would like to be able to pick any start date and any end date and not having to use the "period cards" anymore.

• Check if we can remove the cards for "date picker" here
• check if we can use any start date
• check fi we can use any end date

Tech Notes

I looked into it and picking arbitrary start and end dates should be doable.

Example: Period starts at 1st, ends at 8th

User picks start date 2, end date 5

=> We treat the days of the period before the start date and past the end date as 0% commitment

We already have code that figures out the payouts when users dynamically adjust commitment

So we can pretend they have selected the containing period, and set to 0% commitment before start, and after end date.

Does this sound reasonable @Gerard097 ?

Period Card displays

We can remove the cards from the date picker, or leave them there.

But I think there's other areas in the UX where we show cards. On those, we need to show cards containing the start and end date (could be the same card - ie, in the above example, just the 1st - 8th card).

Cards should be able to indicate when a user has only part of the period - although this can be implemented at a later date.
The UX could have a visual indication that it's a partial period.
