Description
Require positive hijriYear and Gregorian year 1-9999, then display both as AH / CE.
Calendar coordinates depend on an era, origin, day-start rule, and sometimes an arithmetic rather than observational convention. A supplied coordinate difference does not resolve those choices.
Require positive hijriYear and Gregorian year 1-9999, then display both as AH / CE.
When to use this tool
Use Arabic Imprint Hijri Gregorian Dual Year Label when you need a documented calendar convention or source-coordinate comparison.
How to use the tool and how it works
- Enter hijriYear, gregorianYear. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.

{
"input": {
"hijriYear": 1447,
"gregorianYear": 2026
},
"output": {
"label": "1447 AH / 2026 CE"
}
}Limitations and assumptions
- The two years are independently supplied, not converted or checked for overlapping calendar periods or historical accuracy.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Consult the source calendar and authoritative date information for actual observance, conversion, or historical dating.
