Description
Calculate supplied print-minus-online publication days.
Bibliographic records distinguish editions, publication states, author identifiers, dates and fractional-credit conventions. A DOI-shaped string may not resolve, and an ORCID-shaped string can fail its checksum. Supplied status and source labels organize evidence without establishing authorship, publication validity or a complete impact measure.
Calculate supplied print-minus-online publication days.
When to use this tool
Use Publication Online Print Date Delta when you already have onlineDate, printDate and need to calculate supplied print-minus-online publication days.
How to use the tool and how it works
- Enter onlineDate, printDate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read printMinusOnlineDays. Use the output convention below.
Parse both real UTC YYYY-MM-DD dates; return (print-online)/86400000.1

}Limitations and assumptions
- Negative gaps are accepted. Dates and meanings are supplied; no publication history, timezone or authoritative first-publication date is retrieved.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Check original publications, authoritative identifier records and current publisher notices. Define counting scope, credit allocation and date meaning before combining local labels or author overlaps into a bibliometric analysis.
