Introduction

Wilsons & Co. (Sharrow) Ltd. manufacture tobacco products at their Sharrow Mills facility in Sheffield, England, and they often incorporate on their product packaging a production date code.

Sharrow Mills 2021 Production Date Code Format

A production date code format that was introduced at Sharrow Mills in 2021-11 is AAAABBC, where value AAAA equals a four-digit production month-year code, value BB plainly expresses the day of the month in the Gregorian calendar system of production in two-digit format, and value C equals a single-letter production shift code.

Calculating the Date From This Production Date Code Format

To calculate the date of production of a Sharrow Mills tobacco product from a production date code of this format with the real code 173927A for the sake of example:

• Begin by separating the production date code into its three constituent segments which are a four-digit segment followed by a two-digit segment followed by a single letter segment, like so: 1739-27-A.
• The first segment is a month-year code for which the index value 1737 corresponds to 2021-11 and increments by a value of one for each subsequent month. A convenient way to discern the production month-year is to reference the month-year code chart provided. In this example the code is 1739 which corresponds to 2022-01.
• The second segment plainly expresses the day of the month of production in the Gregorian calendar system. In this example the value is 27 which indicates the twenty-seventh day of the month.
• The third segment is a production shift code that has two possible values: A for am production and B for pm production. In this example the code is A which corresponds to am production.
• Contextualise the production values by combining them. In this example the production date code conveys a date of production of 2022-01-27 am.

Sharrow Mills 2013 Production Date Code Format

A production date code format that was introduced at Sharrow Mills in 2013 is AAA BBC, where value AAA equals the number of the day of the year of production in the Gregorian calendar system expressed in three-digit format, value BB equals the final two digits of the year of production in the Gregorian calendar system, and value C equals a single-letter production shift code.

Calculating the Date From This Production Date Code Format

To calculate the date of production of a Sharrow Mills tobacco product from a production date code of this format with the real code 147 21A for the sake of example:

• The first segment of the production date code plainly expresses the day of the year of production in the Gregorian calendar system. In this example the value is 147 which indicates day one-hundred and forty-seven.
• The second segment of the code comprises two units:
  • A two-digit number that expresses the year of production in the Gregorian calendar system. In this example the value is 21 which indicates the year 2021.
  • A one-character letter suffix that is a production shift code that has two possible values: A for am production and B for pm production. In this example the code is A which corresponds to am production.
• To arrive at the specific date of production, use a calendar to convert the day number of the particular year into the date of the year. In this example, day one-hundred and forty-seven of the year 2021 corresponds to 2021-05-27.
