What it is and why it matters
The record chart stores the source data and your notes so that you can return to the calculation. chart may relate to a person, event or question time.
When to use it
- For a new client, educational example or event.
- When you have specified the time or place and need to list the chart.
Terms explained
- Natal chart
- The sky chart for the time and place of birth. It provides the starting chart for comparisons with forecasting techniques.
- Asc and MC
- The Ascendant (Asc) is associated with the intersection of the ecliptic and the eastern horizon. The Midheaven (MC) is associated with the upper part of the local meridian. Both depend on time and location.
Where to find it
“+” to the left; the “Editing data chart” pencil in the top panel.
How to use it
- For a new record, press “+”. For an existing one, open the chart first in the list, then press the pencil.
- Enter your name, date and local time. Select a location through search, check the belt or fixed UTC correction.
- If necessary, fill out the gender, record view, tags and notes. Imported photos are shown in the record. Julian dates can be transferred from ZET; a separate calendar switch in the form is not yet available.
- Save the changes. Open the Data tab and turn the time entered with the intended UT.
Settings and options
Select an option to learn how it works and when to use it. The label beside its name shows whether it affects calculations, chart appearance or data.
Name or titleData
I know the name of the record in the database.
- What changes
- Helps to find a person or event; does not affect the coordinates of planets.
- When to use it
- Use distinguishing names, especially for one person’s events.
SexData
Sign of the record: not specified, male or female.
- What changes
- It is stored as a characteristic of the base; it does not move planets or cusps on its own.
- When to use it
- Select if required for your library or import; an unknown value can be left empty.
Record type: Person / Event / HoraryData
Determine the role of the record: person, event or other available database type.
- What changes
- Imported events may have a connection with a press for the condensation method. In this form, there is no separate choice of parent record; the type itself does not establish such a connection.
- When to use it
- Use the "Event" type for a separate recording of the event; for birth time rectification also check the imported attachment to the native.
DateData
Calendar date of birth or event, as in the source.
- What changes
- Together with time and time zone sets the calculation moment. Format DD.MM.RRRR; the impossible date the program will reject.
- When to use it
- For historical records, add a calendar after import.
TimeData
Local clock time of the event, GG:XH or GG:XH:SS.
- What changes
- Changes moment, angles and houses; the UT program removes local time and corrections.
- When to use it
- Enter the time from the document. If it is approximate, record uncertainty in the research materials; do not perceive the conditional 12:00 as the exact time.
LocationData
Search for a settlement in the built-in atlas.
- What changes
- It is the choice of the result that sets the coordinates and time zone; the text of the name entered without the selection does not guarantee their update.
- When to use it
- Select the right city according to the country. If there is no result, manually enter coordinates and belt.
LatitudeData
North or south of the equator.
- What changes
- It affects the horizon, houses and local astronomical events. South can be set S or a negative number.
- When to use it
- Check the location after hand-input: for example 50.45 or 50°27′ N; boundaries −90...90°.
LongitudeData
Eastern or western of the original meridian.
- What changes
- Affects the local meridian and houses. West — W or negative number.
- When to use it
- Example 30.52 or 30°31′ E; boundaries −180...180°. This is the geographical longitude, not the longitude of the planet in the zodiac.
Time zoneData
Local time translation rules to UT for place and date, such as Europe/Kyiv.
- What changes
- The automatic mode uses historical data, including time transitions. The belt is not a permanent repair for all years.
- When to use it
- Select the event belt. Check the warnings for historical dates and clock shifts.
Set GMT offset manuallyCalculation
Disables the automatic selection of time correction and allows you to specify it yourself.
- What changes
- Enabled: The "Shift from GMT" field is used, and the time zone does not define the correction. Off: the historical database selects the correction.
- When to use it
- Leave off if there is no proven source of another correction. The manual value should already include the desired summer or other time.
- Example
- Local 12:00 and the shift +02:00 give 10:00 UT. Add two hours to the time entered before this is not necessary.
GMT offsetData
The manual difference between local time and UTC is +GG:X or −GG:X.
- What changes
- Changes UT and the entire calculation. Available after enabling manual shift.
- When to use it
- The change is to be specified on the date of the event. +02:00 means that the local time is two hours ahead of UTC.
Local mean timeCalculation
Calculates the time shift by geographical longitude, as in local average solar time.
- What changes
- Completes manual correction. This is a different standard time than modern belt.
- When to use it
- Use only when the historical source gives a local average time; the current birth record usually does not require this.
House systemCalculation
Houses are the 12 sectors of a chart. In astrology, they represent topics such as identity, resources, relationships and work. The house system determines the boundaries of these sectors, called cusps. You choose it separately from the zodiac.
- What changes
- Changing the system moves the cusps. A planet’s house, house rulers and formulas involving cusps may change. Choosing a different house system does not itself move a planet through the zodiac. Asc and MC do not coincide with the first and tenth house cusps in every system.
- When to use it
- For beginners: keep Placidus for your first chart unless your textbook specifies another system. For practitioners: use the system required by your method and record it in your report. Select the same system when comparing programs.
- Example
- Suppose Asc is at 18° Taurus. In Equal houses, the first house starts at 18° Taurus; in Whole sign houses, it starts at 0° Taurus. A planet at 10° Taurus may be assigned to a different house even though its longitude has not changed.
Available options
- Placidus
- Division of diurnal semi-arcs; the default for a new chart.
- Koch
- Division based on the rising time of the MC degree.
- Porphyry
- Each quadrant of the ecliptic is divided into three equal parts.
- Regiomontanus
- Projection of equal divisions of the equator through the horizon.
- Campanus
- Division of the prime vertical passing through the east point and zenith.
- Equal houses
- Equal 30° houses starting at the exact Asc.
- Whole sign houses
- The entire sign containing Asc becomes the first house.
- Alcabitius
- Division of the Asc semi-arc on the equator.
- Morinus
- Transformation of equal equatorial divisions into ecliptic coordinates.
- Topocentric
- The Polich–Page algorithm, similar to Placidus.
- Meridian
- Equal right-ascension steps from the meridian.
- Vehlow
- Equal 30° houses, with Asc in the middle of the first house.
- Sripati
- Boundaries halfway between the Porphyry cusps.
- Krusinski–Pisa–Goelzer
- Projection of divisions of the Asc–zenith circle.
- Horizontal
- Projection of equally spaced horizon directions.
- APC
- Division of the parallel of declination through Asc.
- Equal houses from MC
- Equal 30° houses, with MC beginning the tenth house.
- Equal houses from 0° Aries
- The first house always starts at Aries.
- Carter, poli-equatorial
- Equal right-ascension steps from Asc.
- Pullen, sinusoidal delta
- Unequal quadrant division using sinusoidal differences.
- Pullen, sinusoidal ratio
- Unequal quadrant division using sinusoidal ratios.
- Sunshine (Treindl)
- Houses calculated with the Sun’s declination taken into account.
At a latitude where the selected system cannot be calculated, Zorya Astro reports a fallback to Porphyry. Check the system actually used in the Houses tab. The Topocentric house system and the Topocentric positions setting control different calculations.

Link to this controlZodiac: Tropical / SiderealCalculation
The zodiac is a scale of 12 equal signs of 30° used to express planetary positions. The tropical zodiac starts at the March equinox. The sidereal zodiac uses a different origin tied to a stellar reference; the ayanamsha specifies the offset. Sidereal signs are also equal in size; they are different from the unequal astronomical constellations.
- What changes
- The degrees, and often the signs, of planets and angles change, and dependent tables are recalculated. Because the offset is shared, the longitude difference between two planets does not itself change. In Whole sign houses, changing the zodiac can also change houses because they depend on the sign of Asc.
- When to use it
- Keep Tropical if you are studying a tropical method. Choose Sidereal for a sidereal school and to reproduce its examples. Professional reports should also name the ayanamsha.
- Example
- Illustrative example: the tropical Sun is at 10° Aries and the ayanamsha is 24°. Its sidereal position is 16° Pisces: 10° − 24° = −14°, or 346° around the circle. The birth date has not changed; the coordinate origin has.
Available options
- Tropical
- The usual starting mode of the new chart; Ayeamsha field is inactive.
- Sidereal
- Opens the choice of Ayaamsha; applies it to sidereal calculation.
Sidereal is not a “more accurate” setting. It is a choice of tradition and coordinates. The 24° value is illustrative: see Data for the actual ayanamsha on the chart date.
Link to this controlAyanamshaCalculation
The angular offset between the tropical zodiac and a particular sidereal zodiac. Different schools define different origins, so “sidereal” alone is not enough to reproduce a chart.
- What changes
- Available after selecting Sidereal. Changing the ayanamsha recalculates sidereal longitudes. Near boundaries, the sign, nakshatra, varga and initial dasha balance may change.
- When to use it
- Start with Lahiri unless your teaching method requires another ayanamsha. When comparing with a colleague, check the ayanamsha, date and node mode. The Vedic and Periods screens have their own ayanamsha selectors; check those separately.
Available options
- Lahiri
- Zorya Astro’s default, for reproducing Lahiri calculations.
- Raman
- B. V. Raman’s variant, with its own offset.
- Krishnamurti
- For methods that explicitly require this variant, including KP.
- Fagan–Bradley
- A separate standard in the Western sidereal tradition.
- Yukteshwar
- The Swiss Ephemeris definition for this school.
- True Chitra
- Spica is anchored at 0° Libra.
- Galactic center at 0° Sagittarius
- The coordinate origin is anchored to the Galactic Center.
The field is disabled in Tropical mode. A greyed-out field is expected because this offset is not applied in that mode.

Link to this controlTopocentric positionsCalculation
Geocentric calculation looks from the center of the Earth, topocentric — from the observation spot on its surface. The difference is due to parallax; it is especially noticeable for nearby Moon.
- What changes
- Enabled: the position is asked for the chart location. Off: standard geocentric. Change can affect the exact longitude and aspects. This is not the choice of topocentric system houses.
- When to use it
- Leave off for the usual geocentric natal chart. Turn on if your methodology or control calculation clearly uses topocentric coordinates; location coordinates should be correct.
- Example
- Compare Longitude Moon before and after switching, keeping the date and system houses unchanged. So you will see the effect of the observation point.
PhotosAction
Open the attached photo if the file is available.
- What changes
- Unavailable file is marked separately; the astronomical calculations are not affected by the photo.
- When to use it
- To check the materials of the archive; when transferring, check whether the photo has been imported.
Calculate and save / Cancel / Delete chart…Action
Save checks the fields and saves the chart; canceling closes the unsaved form; deleting removes the existing record after confirmation.
- What changes
- This is action over the base, not just over the display. After saving, open "Data" to control UT and settings.
- When to use it
- Before removing the chart, make a backup copy.
The result
The program lists the chart and saves the record in the browser database.
Worked example
This is a teaching example; results for your chart may differ.
- Situation
- The client specified the time of birth from 14:00 to 14:20.
- What to do
- Edit time in the available record and compare houses and angles.
- How to read the result
- You will see what conclusions were based on the incorrect time, and you will keep the corrected foundation.
For professional practice
Tags and notes help keep a cartograph and mark the origin of data.
What to check for a precise comparison
Record the source and time accuracy in your notes. Save a copy of your previous data before changing an important record.
Keep in mind
The birth time is entered local. Do not translate it to UTC before entering if you use the city time zone.
Search chart on the left and tags help to quickly return to the record. Removal chart requires confirmation.
