Fixing Your 1-60 Number Regex & Avoiding Partial Matches

Got it, let's tackle this regex issue head-on. Your current pattern [0-6][0-9] has two main problems: it matches invalid values like 00 (which falls outside your 1-60 range) and it doesn't anchor to the boundaries of the target—so it'll happily grab a valid substring from a longer number like 950 (hence the unwanted 50 match you're seeing).

Here's how to fix it, tailored to two common use cases:

Case 1: Match an entire input string (e.g., user enters a single number)

Use start (^) and end ($) anchors to ensure the entire string is a valid 1-60 number:

^(?:[1-9]|[1-5][0-9]|60)$

Breakdown of this pattern:

^ = Marks the start of the string
(?:...) = A non-capturing group to group our valid number options without storing extra data
[1-9] = Matches single-digit numbers 1-9 (avoids 0)
[1-5][0-9] = Matches two-digit numbers 10-59
60 = Explicitly matches the upper limit of your range
$ = Marks the end of the string

This will reject inputs like 950 entirely, and only accept numbers strictly between 1-60.

Case 2: Match standalone numbers within a larger text (e.g., "The limit is 50, not 950")

If you need to find valid 1-60 numbers embedded in text without matching parts of longer numbers, use word boundaries (\b) instead of start/end anchors:

\b(?:[1-9]|[1-5][0-9]|60)\b

The \b ensures the number is surrounded by non-word characters (spaces, punctuation, etc.) or the start/end of the text—so it won't pick out 50 from 950, but will match 50 when it's a standalone number.
