Why it works this way
Quick answers, kept to yourself
The date you came for comes first. Explanations, sources, and the longer story sit underneath it.
Persian and English, equally
Neither language is a translation of the other. Both get the same care, and a layout for their own direction.
Birthday details, ready to use
Your exact age, the weekday you were born on, your next birthday, and both zodiac signs — all in your browser.
Meeting across two working weeks
Iran's week runs Saturday to Wednesday, so the overlap with a Monday-to-Friday week is narrower than the clocks suggest. Pick a date and a time and see whether it lands inside both.
