Virgo
Virgo is the sixth sign of the zodiac, and in the Persian solar calendar it is also the sixth month — known in Persian as Sonbola, the ear of grain. Here the sign is not laid over the calendar; it is the calendar's own month.

Where Virgo sits among the borj
The twelve zodiac signs entered Persian usage as the borj, and the solar calendar took them as the names of its months. The year opens with the spring signs and runs in the familiar order, so Virgo falls in the sixth place: the last of the summer months, at the point where the long heat begins to give way.
Its Persian name, Sonbola, means the ear of grain — the same image the Greek and Arabic names carry, of a figure holding a stalk of wheat. That name is not only historical. The Solar Hijri calendar used in Afghanistan still keeps the borj as its month names, so a letter dated in Sonbola there is dated in Virgo, without any translation needed.
In Iran the months carry older Persian names instead, but the borj remained in the language of astronomy, almanacs and everyday speech, and the correspondence between the two sets of names is exact: the sixth month of one is the sixth month of the other.
What the tradition associates with this borj
In the tradition, Virgo is counted among the earth borj, and earth is read as the settled, productive element — the one associated with what can be measured, stored and made to last. Placed at the close of summer, this borj is traditionally tied to the harvest: the grain in its emblem is gathered grain, and the qualities the tradition gathers around it are the qualities of gathering — sorting, weighing, setting things in order.
The tradition assigns this borj to Mercury, and with that assignment come the attributes it gives that planet: clear attention, skill in language and number, and a turn of mind that works by distinguishing one thing from another. From this, traditional readings describe the borj as discerning and observant, attentive to the small parts that make a whole work, and patient with the kind of task that rewards care rather than speed.
Craft and useful work sit close to this borj in Persian usage. The tradition speaks of thoroughness, of a preference for what is well made over what is merely large, and of modesty in manner — a readiness to do the necessary thing without display. Where the older readings record a difficulty, it is the exacting side of that same care: a standard held so finely that little is judged finished. The tradition names this plainly and treats it as the cost of the borj's precision, not as a flaw apart from it.
These are readings the tradition carries, recorded and retold over centuries. They describe the sign, not any person born in its month.
The sign, the month, and why the dates move
The Persian year begins at the vernal equinox, at the true astronomical moment, and the months were cut along the zodiac from there. That is why the sign follows the month here rather than the other way round: when the sixth month begins, Virgo begins. The classical quality given to this sign is mutable, which in plain terms means it holds the closing stretch of its season — summer's last month, already turning toward autumn and handing the year on to the sign that follows.
Because the equinox does not fall at the same clock time each year, the first day of the Persian year shifts, and every month shifts with it. Translated into Gregorian terms, the day Virgo begins is not the same day in every year; across a long run of years it lands on more than one date. A printed table that gives a single fixed range will therefore be right for most years and wrong for some.
This product treats that mismatch as the table's approximation rather than as an error of its own. It maps the sign to the calendar's month boundaries as the calendar itself computes them — no degrees of solar longitude, no cusps, no time of day, none of which a civil birth date could support in any case.
What Shahrivar, the month itself, is called in Iran and in Afghanistan
When Virgo began
The Persian year starts at the spring equinox, so each month starts on whichever Gregorian day the equinox falls on. That is why these dates move.
Across the 101 years below, Virgo began on 3 different Gregorian dates. A printed table prints one of them.
