Write Blog Dates Readers Can Interpret

Write a date clearly only after you know what it means; if its numeric order is unknown, keep the original string and check the source. Naming the month helps a reader distinguish April 3 from March 4. It cannot tell you which date an unexplained 03/04/26 was meant to represent.

This card is for dates mentioned inside your article: a workshop, an interview or an event. The article's publication and update dates are separate information.

Separate the source value from the display

Keep two entries in your notes: the value you received and the meaning the source supports. Then choose how to display that supported date in your prose.

W3C's date-format guidance explains how numeric orders can confuse readers across locales. It recommends making the month explicit and using four digits for Gregorian years when you need to avoid ambiguity. It also discusses a year-month-day form and its tradeoffs.

For the examples here, our declared English house style is month name, day, four-digit year: April 3, 2026. March 4, 2026 follows the same style. You could instead choose 3 April 2026; naming the month makes the order apparent. W3C does not require the US order used in this card.

A completed date card

These are invented inputs for a fictional craft-session article. The first two records explicitly supply Gregorian calendar dates in year-month-day order. The third supplies only a bare string, with no order or year interpretation.

The last row stays unresolved even if the article is written in US English. Your page's language, your usual date style or a reader's browser preference does not establish what the original writer intended.

If you must mention an unresolved record before you can check it, distinguish the string from an event-date claim: The note contains 03/04/26; the date has not been established. When the actual date matters to the article, resolve it before publishing that claim.

Download the filled date card and the three-row teaching CSV. The CSV preserves every supplied string. Its unknown row has no normalized date or invented English display.

Keep both ends of a span

The fictional article also supplies a separate workshop span: a start date of 2026-04-03 and an end date of 2026-04-05, both Gregorian dates in year-month-day order.

Write it as April 3 to April 5, 2026. The filled card records the start and end separately, so a shortened display does not discard either input. These dates are teaching content, not dates of a real workshop or this article's publication.

Use the card on your own draft

1. Copy the original value exactly. Keep its source location beside it so you can return to the record.

2. Record the declared meaning. Look for an explicit date, stated numeric order and full year. Leave any missing part unknown.

3. Choose a consistent prose display. For a supported Gregorian date, name the month and write the full year. Keep the declared year-month-day value in a separate field when you need one for data exchange.

4. Compare the finished wording with the source. Check the day, month and year; for a range, check both endpoints. If the wording requires a guess, stop and ask for the missing meaning.

The downloads are a record of supplied meaning and display choices. They do not convert calendars, determine time zones or demonstrate how a spreadsheet, parser or publishing system will interpret a string.

When you are choosing what information the article needs in the first place, use the article brief. The blog-writing guide helps turn those notes into a finished post, and keyword research for bloggers connects the post to a reader's question.
