Why does time.Parse reject my YYYY-MM-DD-style format string?
KitForma editorial guide. Go layouts use a reference timestamp’s concrete components rather than letter-token formats from other languages. Copying another language’s format can parse the wrong pattern.
Step-by-step guidance
Go layouts use a reference timestamp’s concrete components rather than letter-token formats from other languages. Copying another language’s format can parse the wrong pattern.
Use the matching Go layout and state timezone interpretation:
package main
import ("fmt"; "time")
func main() {
d, err := time.Parse("2006-01-02", "2026-10-02")
if err != nil { panic(err) }
fmt.Println(d.Year(), d.Month(), d.Day())
}Test invalid calendar dates and required offsets. A timezone-free date is not automatically a local appointment instant. Successful parsing proves syntax acceptance, not that the selected zone or recurring-schedule semantics match the business requirement.
