六(ろっ)ヶ月(げつ)

六(ろく) (six) + ヶ月(げつ) (months counter), with sokuon assimilation to ろっ before か.

Writing variants

The middle character can be written as ヶ, ヵ, か, カ, or 箇(か) — all read か:

• 六(ろっ)ヶ月(げつ) (most common in print)
• 六(ろっ)箇月(かげつ) (formal/legal)
• 六(ろっ)か月(げつ) (informal)

The small ヶ is the standard learner-facing form. Note that this ヶ is not a katakana 'ke' but an abbreviation of 箇(か).
