The Vedic definition of day is from sunrise to sunrise and NOT from an arbitrary midnight to midnight (00:00 - 24:00). Every component of the Gaurabda Panchanga is determined by a celestial event, not human arbitrariness. If sunrise time is 06:00, then the day runs from 06:00 - 30:00. The hours past midnight till next sunrise are added to 24:00. For each day, the Panchanga data is organised as:
1. The first line on the left shows the Gaudiya-Vaishnava era called Gaurabda, the luni-solar year counted from the advent of Lord Caitanya Mahaprabhu in 1486. Then an icon depicts the Tithi (luni-solar day) at sunrise, and the Masa (luni-solar month), named after an incarnation/expansion of Lord Krishna. On the right are header tabs to display the changing timelines of the Panchanga's major components.
2. The second line has the civil calendar date; the Vara (day of week); the Paksha (luni-solar half-month, either Krishna (dark) or Gaura (bright) to denote the waning Moon and waxing Moon respectively); the Tithi (luni-solar day) at sunrise; and the Vedic solar month and solar day number respectively.
3. On the right, a series of timelines track changes to the major components of the Pancanga: Tithi, Karana, Yoga, Nakshatra-Pada. Each entity is tagged by a number denoting its order as listed in the reference tables (in the inside covers). When a change occurs, the first two columns on that timeline will generally carry the name of the new entity and the time of change. Timelines can also indicate Tri-Sandhya (sunrise, noon, sunset) timings, start/end of Brahma-muhurtha (the spiritually most auspicious period, which starts about 96 minutes before sunrise), start/end of Rahu kala (an inauspicious period) and other changes.
4. The third line on the left displays the 12 Rasi signs of the Vedic sidereal zodiac in which the movement of the Lagna (ascendant) will be tracked daily. For brevity's sake, the zodiacal signs and planets are denoted by their symbols. The Sanskrit and English names for the signs and planets represented by these symbols are given in the reference tables.
5. The next two (sometimes one) line/s on the left indicate the Lagna (ascendant) changes. The Lagna is the same sign as the Sun at sunrise. The timings of the subsequent rising signs, i.e. the Lagna changes, are given in order in the Lagna line/s till next sunrise.
6. Then the Rasi chart and the Navamsa chart are presented, showing the longitudes and positions of the Navagraha (nine planets) at sunrise daily. If a planet moves into new Navamsa (one of the nine sub-divisions of a Rasi) later the same day, then that time of change is given just after the planet's symbol in the Navamsa chart. This simplifies the work of casting the horoscope charts to mainly copying the Rasi chart and Navamsa chart given daily in this Panchanga, updating any time change given in the Navamsa chart, and deducing the Lagna position from the Lagna line/s.
7. The Moon’s longitude at sunrise is shown in the Rasi chart and subsequent Navamsa position changes of the Moon are reflected in the Nakshatra-Pada column in the timelines on the right.
8. Lastly, if the day coincides with any Gaurabda Calendar event anniversary (fast, feast, festival etc), the event is marked below the Rasi chart.
