Arabic Date Format (DD/MM/YYYY) Regex for Go
/^(0?[1-9]|[12][0-9]|3[01])/(0?[1-9]|1[0-2])/((?:13|14|15)[0-9]{2}|(?:19|20)[0-9]{2})$/What this pattern does
This page provides a comprehensive, battle-tested regular expression for matching arabic date format (dd/mm/yyyy), ported and verified for Go. A rigorously tested regex reduces debugging time and protects your application from edge-case failures. The snippet below is ready to drop into your Go project — whether you're validating in a Gin handler, a gRPC service, or a command-line tool.
Go Implementation
// Arabic Date Format (DD/MM/YYYY)
// ReDoS-safe | RegexVault — Localization > Date Formats
package validation
import "regexp"
var arabicDateFormatDdmmyyyyRe = regexp.MustCompile(`^(0?[1-9]|[12][0-9]|3[01])/(0?[1-9]|1[0-2])/((?:13|14|15)[0-9]{2}|(?:19|20)[0-9]{2})$`)
func ValidateArabicDateFormatDdmmyyyy(s string) bool {
return arabicDateFormatDdmmyyyyRe.MatchString(s)
}
// Example
// fmt.Println(ValidateArabicDateFormatDdmmyyyy("15/01/2024")) // trueTest Cases
Matches (Valid) | Rejects (Invalid) |

When to use this pattern
This pattern is drawn from the Localization > Date Formats category and carries a ReDoS-safe certification. That matters for Go developers because Go's RE2 engine is inherently safe from catastrophic backtracking, but this pattern has been additionally verified for correctness. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.
Common Pitfalls
The Islamic Hijri calendar has 354 or 355 days per year (lunar). Converting Hijri to Gregorian requires an algorithm, not simple arithmetic. The Persian Solar Hijri (Jalali) calendar used in Iran differs from the Arabic Hijri.
Technical Notes
Most Arabic-speaking countries use the Gregorian calendar for civil purposes and the Hijri (Islamic lunar) calendar for religious purposes. The Hijri calendar currently has years starting with 14xx (1445 AH = 2023-24 CE). Saudi Arabia switched to Gregorian for official use in 2016.
