In the Odia calendar, which is a traditional lunisolar calendar used in the Indian state of Odisha, the concept of a “lunar week” is not explicitly defined in the same way it might be in other calendars or cultures. However, the Odia calendar is based on lunar months, with each month beginning with the new moon and consisting of either 29 or 30 days.
The days of the week in the Odia calendar are named after celestial bodies and are as follows:
| Day (Odia) | Celestial object | Equivalent | Day (Gregorian) |
|---|---|---|---|
| ସୋମବାର Somabara | Chandra | Moon | Monday |
| ମଙ୍ଗଳବାର Mangalbara | Mangala | Mars | Tuesday |
| ବୁଧବାର Budhabara | Budha | Mercury | Wednesday |
| ଗୁରୁବାର Gurubara | Brihaspati | Jupiter | Thursday |
| ଶୁକ୍ରବାର Sukrabara | Shukra | Venus | Friday |
| ଶନିବାର Sanibara | Shani | Saturn | Saturday |
| ରବିବାର Rabibara | Surya | Sun | Sunday |
While these days are not directly tied to lunar phases, the lunar cycle does play a significant role in determining the timing of festivals and auspicious occasions in the Odia calendar. Therefore, the lunar phases are still observed and influential in the scheduling of events within the calendar system.
Lunar Phases
Each month begins with the Shukla Paksha (waxing moon) and ends with either Purnima (full moon) or Amavasya (new moon). However, these phases are not used to define weeks.
