## What it is
ByStar is a Ruby gem that adds time-based query scopes to ActiveRecord and Mongoid models, letting you find records by year, month, fortnight, week, day, or arbitrary time ranges. It provides convenient finder methods like by_year, by_month, between_times, before, and after for time-oriented data queries.

## Use cases
- query posts created in a given year or month
- find records between two dates or times
- get all records from yesterday or last week
- find the next or previous record relative to a given record
- query records by calendar month, weekend, or fortnight
- filter ActiveRecord or Mongoid models by time ranges

## When to choose
- you use Rails ActiveRecord or Mongoid and frequently query by time periods
- you want reliable, tested scopes for year/month/week/fortnight queries instead of hand-writing date math
- you need calendar-aware queries like calendar months or weekends

## When to avoid
- you don't use ActiveRecord or Mongoid (e.g. Sequel, ROM, or non-Ruby stacks)
- your time queries are too complex or custom for the provided scopes
- you need a non-Ruby ORM time-querying solution

## Facets
- artifact type: library
- maturity: maintenance
- function: orm, database, date-time
- domain: databases, web-development, developer-tools
- platform: ruby, jvm
- tags: activerecord, mongoid, time-based-queries, rails, gem
