Hello, I want to know if this is possible.
A user enters a service start date in the current year, and the service end date next year.
I need to calculate first the days of the current year, and then the days of the next year, since the price is per day and this year has a price, and it will change for the next year.
Is this possible with Date Time Calculator?
The use case described can’t be done using Gravity Forms out of the box. I don’t know if using the Gravity Wiz’s GP Date Time Calculator perk could be an option in this case, I would recommend you to reach Gravity Wiz staff about it: Have a question about Gravity Perks? - Gravity Wiz
If they can’t help, Gravity Forms are official partners with Codeable, who are the #1 WordPress outsourcing service. They can provide quality development from hand-picked Gravity Forms specialists for any project size and budget. Additionally, they can also provide you with a no obligation estimate of what the project may cost up front. You can reach them via this link.
You can also post to our Community Forum Job Board, We do not vet any of the individual developers there, it is an open forum for all, but our community is certainly full of talented folks!
Hi Juan, Dave from Gravity Wiz here, one question for you. I understand the the user selects their own start date. Do they also select their end date? or is the end date always a set time period from the start date (e.g. a year)?
Yes, the user selects the start date and end date.
I was able to solve it with the help of Date Time Calculator.
Epic! Sorry for the slow reply. Had a busy one yesterday. 
Glad you were able to figure out the solution.
