13 weeks is approximately 3 months.

Explanation:

• 1 month is roughly 4.33 weeks (since 52 weeks ÷ 12 months ≈ 4.33 weeks/month).
• So, 13 weeks ÷ 4.33 weeks/month ≈ 3 months.

If you want a more exact conversion in days:

• 13 weeks × 7 days/week = 91 days
• 91 days ÷ 30.44 days/month (average month length) ≈ 3 months
