If Dwadasi occurs on Fridays, can one eat gooseberry? Are there any regulations that stipulate when gooseberries can be consumed?

If Dwadasi falls on Fridays, one can partake gooseberry.
Notes:
As a rule, gooseberries have not partaken during night times, Sundays, Tuesdays, and Fridays.
If Dwadasi falls on the aforementioned days, one must partake gooseberries as Dwadasi is considered to be more sacred than these days and including gooseberries in the food is important
