Norwegian Bokmål spells dates with an ordinal day, the month name, and the year
written out in full. The year reads as a cardinal where the final group is
joined to the thousands with the word og. This tool produces that exact form
for any date.
How it works
The day comes from a table of Bokmål ordinals from første (1st) to
trettiførste (31st), so the 4th is fjerde. The month is taken from the
standard list (juni for June). The year is built as a cardinal: tens and
units join directly in the modern order (tjueseks = 26), and when the final
group is under one hundred it is attached to the thousands with og. So 2026
spells as to tusen og tjueseks.
Combined, 04.06.2026 reads as fjerde juni to tusen og tjueseks.
Tips and example
Use the written form on invitations, certificates, and formal correspondence
where spelled-out dates read more carefully than digits. Note the modern
tens-before-units order: write tjueseks rather than the archaic seks og tjue. The og before the final group is required in years like to tusen og tjueseks but is dropped when the remainder spans a hundred or more, which the
tool resolves automatically.
