If what you mean by "safe" is avoiding pregnancy, the only safe time is long after menopause is complete. Seriously. Those dangerous fertile periods vary from woman to woman, and even in one woman they vary month to month. It's also variable how long a man's sperm will live and lurk waiting for an egg to appear, depending on how hospitable the woman's chemistry is to the little swimmers. There's an old joke: "What do you call couples who practice the rhythm method?" Answer: "Parents."
It is safe to have sexual intercourse at the following times:
Safe from what? Pregnancy or diseases. No contraception is 100% effective in protecting pregnancy or Infectious Diseases.
If you mean to not conceive then no time is completely safe. A lady can become pregnant at any time. There is no such thing as a safe time.
It is never safe. Please ask your partner to use condom. Your partner may be partner of others also and he may gift you HIV or other sexually transmitted diseases.
