Batch identifiers and labeled dates (JSON)
For each input date output prefix-YYYYMMDD-rowNumber and production date+shelf-life days.
Symbols and units
- a
- Production dates (ISO dates); enter JSON
- b
- User shelf life (days)
- c
- Batch prefix
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-defined calendar shelf life and date-derived code; does not establish shelf life or labeling compliance. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. Valid ISO dates, 0..3650 shelf-life days, nonempty prefix; codes unique within this input list only.
