1. What Are Safe Days?

Safe days refer to periods in a woman's menstrual cycle when the likelihood of pregnancy is lowest. These typically occur during the first week after menstruation and the week before the next period begins.

2. How Does the Calculator Work?

The calculator uses the standard safe days calculation:

Where:

• Days 1-7 — First safe period after menstruation
• Last 7 days — Second safe period before next period
• Middle days — Fertile period with higher pregnancy risk

Explanation: This method assumes a regular menstrual cycle and identifies days when ovulation is least likely to occur.

3. Importance of Safe Days Calculation

Details: Understanding safe days helps in natural family planning, fertility awareness, and making informed decisions about contraception and pregnancy prevention.

4. Using the Calculator

Tips: Enter your typical cycle length (usually 21-35 days) and current cycle day. The calculator will determine if today is a safe day or fertile day.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the safe days method?
A: The calendar method is about 76-88% effective with perfect use. It works best for women with very regular cycles.

Q5: Should I rely solely on safe days for contraception?
