In context of nepal, there is no system of AD here we have BS system. I just am able to convert BS to AD. I just want user to enter the date of birth as it is in same format as AD. But I want the user to give the instruction as we have yyyy-mm-dd as today is 2077-10-27 and if the user input the date manually as 10-27-2077 it should give an error please input as yyyy-mm-dd

As your example uses date type, only valid dates can be selected/entered in date widget KoBo/ODK Collect and in Enketo. So, what exactly is your validation question?
Otherwise you could use:
- a constraint (with constraint_message) on the first field, using regex(…). instead of your 2nd field
- the hint feature in KoBo/Collect, for better (layout) separation of the hint from the question label.
