太陽暦

1. Origins, structure, and basic meaning

• Structure: 太陽暦 combines 太陽, sun, with 暦, calendar system, and denotes a calendar system based on the sun.
• Basic usage: A calendar may 太陽暦を基にする, and the system can be compared with 太陰暦.

2. Common pitfalls and similar expressions

• System versus one calendar object
  • 太陽暦 names a system for reckoning dates and years, not a single printed calendar.
• Contrast with 太陰暦
  • The terms identify calendar systems with different astronomical bases and can therefore be set side by side for comparison.
