Vedic astrology for a Mumbai birth

Vedic astrology for a Mumbai birth starts from Indian Standard Time, not from a private city clock. Asia/Kolkata is UTC plus 5 hours 30 minutes in January and in June. Mumbai sits west of the meridian near Mirzapur, so solar noon on the clock falls after 12:00. The city is geocoded, and that offset is applied before the Julian day. Shifting the written time so the Sun looks like it is on noon corrects the same fact twice.

The hospital name is part of the time
Thane, Navi Mumbai, and Mumbai get used as one place in family talk. They are not one place to geocode. All three stay on Asia/Kolkata, and none of them observe daylight saving, but the lagna still follows the coordinates you type as well as the hour. If the record says Mumbai, keep Mumbai. If it names another municipal limit, keep that name.
A later address in the Gulf, in London, or in New Jersey is a different class of mistake. The birth was in Mumbai. The zone at that hour was Indian Standard Time. The city you live in now does not rewrite the hospital clock.
Ask for the time as the nurse wrote it, including whether it was 12-hour or 24-hour. A missing AM or PM moves the chart by twelve hours. That is a larger error than the gap between Mumbai and Thane.
Summer does not move the Mumbai hour
Daylight saving changes a zone offset, and a changed offset can change the lagna. Mumbai never makes that change. Six in the morning is the same offset in midwinter and in May. People who have lived in the United States sometimes add an hour in summer out of habit. On an Indian birth record that addition is wrong.
West of the Mirzapur meridian, 12:00 still falls before solar noon. That is a property of the standard meridian, not a reason to edit the certificate. Leave the hospital time alone and let the ephemeris place the Sun.
If the family only remembers a window, such as early morning or after the evening meal, say so in the notes and cast the chart at the edges of that window. Do not invent a minute that nobody wrote down.
What the sidereal figure actually uses
The figure is sidereal. It uses the Lahiri ayanamsa and planetary positions from the Swiss Ephemeris. It is not a tropical Sun-sign column, and it is not a newspaper horoscope for the week you were born.
Marriage is read from the 7th house, its lord, and the D9 Navamsa. Career is the 10th house and its lord. Timing follows the Vimshottari dasha that is already running. Those are the factors a Mumbai chart shares with any other Indian birth. The city changes the coordinates and the offset. It does not change the rules.
Do not expect the page to name a dasha year, a degree, or a spouse. Those come from the birth time you enter, not from the city name.
A worked order for the first reading
Start with the lagna. If the time is uncertain by half an hour, the lagna may sit near a sign boundary, and the houses that follow will move with it. Check the Moon next, because the Vimshottari sequence is counted from the Moon's nakshatra.
Then read the 7th lord and the 10th lord in the birth chart, and again in D9 for marriage questions. A planet that looks strong in the birth chart and weak in the division you are asking about is not a contradiction. It is two questions.
Transits of Saturn and Jupiter describe the sky now. They do not replace the dasha. A Mumbai resident and a person born in Mumbai who now lives in Dubai share the birth chart. They do not share today's local clock, and today's clock is not what the birth chart was built from.
What you can do on the free chart
A free account can generate the Kundli and chat with the astrologer. Paid plans add a PDF, further divisional charts, and WhatsApp transit alerts. The calculation does not change between those plans. The PDF is a document of the same figure.
Type the birth city as Mumbai when that is the place on the record. The geocoder applies Asia/Kolkata. You do not pick a timezone from a dropdown and then also shift the clock.
If the chart you already have from another site used a tropical zodiac, the signs will not match. That difference is the ayanamsa, not a Mumbai exception. Read this chart as sidereal before you compare yogas line by line.

Frequently asked questions
Does Mumbai have its own time zone in a Vedic chart?
No. Mumbai uses Asia/Kolkata with the rest of India. There is no daylight saving. Solar noon still falls after 12:00 because the city is west of the meridian near Mirzapur.
We live in the Gulf now. Is the birth city still Mumbai?
Yes, when the birth was in Mumbai. The time was Indian Standard Time. The city you live in now is a different place and, outside India, usually a different offset.
Should I correct the birth time so noon matches the Sun?
No. The certificate time is already in Indian Standard Time. Moving it toward solar noon applies the Mirzapur offset a second time.
