As an ASHA worker, I need the system to validate and display the correct dates for Td/TT (Tetanus Toxoid) doses, with specific rules for each dose and the appropriate message when all doses are completed. This will help ensure accurate tracking and prevent errors in the vaccination schedule.

Acceptance Criteria:

1.Date of Td / TT (1st Dose):

• • The system should accept the date for the 1st Dose of Td / TT if it is between 5 weeks from the Last Menstrual Period (LMP) up to 36 weeks of LMP.
  • If a valid date for the 1st Dose is entered, the system should store and display this date.

2.Date of Td / TT (2nd Dose):

• • The system should accept the date for the 2nd Dose of Td / TT only if it is after 4 weeks from the Date of Td / TT (1st Dose) and up to 36 weeks of LMP.
  • If the 2nd Dose is entered, the system should store and display this date.
  • If Td1 (1st Dose) has already been given, display the Given Date for both Td1 and Td2.

3.Td / TT (2nd Dose) Message:

• • If the 2nd Dose (TD 2nd Dose) is given in the Last ANC Visit, display a message:
    "All TD doses are given."

5.Date of Td / TT (Booster Dose):

• • The system should accept the date for the Booster Dose if it is between 5 weeks from LMP up to 36 weeks of LMP.
  • If the Date of Td 1st Dose has already been entered in the Last ANC Visit, disable the Booster Dose date field and prevent the user from editing it.
  • If the Booster Dose has been entered in the Last ANC Visit, display the message:
    "All TD doses have been given." alongside the Booster Dose data field.
    If a pregnant woman has already been immunized with two doses of Inj. Tetanus-Diphtheria during her previous pregnancy (within the past three years), then only one dose of Inj. Td (as Booster dose) is required as early as possible during her current pregnancy.

6.Validation Rules for All Doses:

• • The Td / TT (1st Dose), Td / TT (2nd Dose), and Booster Dose should all be validated according to the above rules.
  • Each dose field should display the corresponding message (e.g., "All TD doses are given" or "All TD doses have been given") based on the inputs and the last ANC visit date
