Where every figure on IndiaRealTime comes from, how often it refreshes, and how derived numbers (like AQI and rankings) are calculated.
IndiaRealTime republishes public and licensed data, not our own measurements. This page is the technical reference for exactly where every figure on the site comes from, how often it refreshes, and how any number we calculate (like AQI or a city/state ranking) is derived - the detail behind the summary on our About Us page.
| Dataset | Source | Refresh |
|---|---|---|
| Weather | WeatherAPI.com | Every 15 minutes |
| Air Quality (AQI) | Central Pollution Control Board (CPCB) via data.gov.in | Every 6 hours |
| Mandi / Commodity Prices | Government of India open data portals (data.gov.in) | Daily (rate-limited fetch) |
| Gold, Silver, Platinum, Palladium | Licensed metals-rate data provider | Daily, ~7 AM IST |
| Fuel (Petrol & Diesel) | Official daily fuel-pricing data | Daily |
| Gas (CNG / PNG / LPG / Autogas) | City Gas Distribution (CGD) licensee pricing | Daily |
| Currency Exchange Rates | Frankfurter exchange-rate API | Daily, ~7 AM IST |
| Panchang (Hindu Almanac) | FreeAstrologyAPI.com | Daily |
| Bank Holidays | State and national bank holiday calendars | Static per-year calendar, checked live |
| Toll Rates | NHAI-published toll plaza rate schedules | Updated on each rate-schedule revision |
| Earthquake Alerts | National seismological monitoring feeds | Checked periodically through the day |
| Weather Alerts | India Meteorological Department (IMD) | Checked periodically through the day |
| Cricket Scores | Live cricket data provider | Hourly, more often around live matches |
Current conditions and today's hourly forecast, taken directly from WeatherAPI.com's forecast endpoint for each tracked city. "Feels like" is recomputed on our side from temperature, humidity and wind rather than trusting the API's own figure.
CPCB's National AQI methodology: PM2.5, PM10, NO₂, SO₂, CO and O₃ sub-indices are each computed from monitored concentrations, and the overall AQI is the WORST of those sub-indices, not an average. City and state rankings are computed fresh from the same live station data on every page load, not a separately maintained table.
Modal, minimum and maximum prices as reported by each APMC market, grouped by market rather than averaged across a city's several mandis, since two mandis in the same city can legitimately report different prices for the same commodity on the same day.
Per-gram 999-fine (24K-equivalent) rate from the provider; other purity tiers (22K, 18K, 958, 950, 925, 900, 500) are derived proportionally from that base rate at each tier's real fineness ratio, except gold's 22K/18K which the provider supplies directly.
State-level price for every state and union territory; city-level price where a source publishes it specifically for that city. 7-day trend is tracked from the daily state figure.
Price for whichever CGD licence area covers a given city; a city outside any covered distribution area simply has no gas price rather than an estimated one.
INR-based rates against major world currencies, fetched once daily and cached; a bounded, non-retried live fetch backs up a missed cron tick.
Computed once per day for a New Delhi reference point. Sunrise, sunset and Rahu Kalam shown on a city page are shifted by roughly 4 minutes per degree of longitude between that city and Delhi for the ~113 cities with known coordinates; other cities show the unshifted national time. Tithi and Nakshatra (lunar-calendar values) are not location-dependent in any way that matters for a single calendar day, so they are shown as-is nationwide.
"Is a bank open today" is computed live against the imported calendar plus a standing rule for Sundays and every 2nd/4th Saturday, rather than a separately cached yes/no flag.
Per-plaza vehicle-class rates as published, imported from official rate schedules; nearest-plaza lookups use each plaza's published coordinates.
Recent events above a minimum magnitude threshold, filtered by state.
Active IMD warnings by affected state, shown until their own stated expiry.
Match, series and player data as reported by the provider.
India's Air Quality Index combines six pollutant readings, PM2.5, PM10, NO₂, SO₂, CO and O₃, from CPCB-monitored stations into a single 0-500 score. Each pollutant gets its own sub-index on the same 0-500 scale; the overall AQI is the worst (highest) of those sub-indices, not an average of all six. This is CPCB's own official National AQI methodology, and it means a single badly-elevated pollutant, commonly PM2.5, can and does drive the whole number even when every other pollutant is in a much better band. City and state AQI rankings shown across the site (e.g. "cleanest of N tracked cities") are computed fresh from the same live station data on every page load, from whichever cities currently have a recent reading, rather than a separately maintained ranking table that could drift out of sync with the number displayed next to it.
