How to create a list of random dates in Ruby

Answer 1

require 'date'

# Generate a random date between two years using Date
def random_date(start_year, end_year)
  # Convert start and end years to timestamps
  start_date = Date.new(start_year, 1, 1)
  end_date   = Date.new(end_year, 12, 31)

  # Uniform distribution over the timestamp range
  range_days = (end_date - start_date).to_i
  offset = rand(0..range_days)

  # Convert back to Date
  start_date + offset
end

dates = []

10.times do
  dates << random_date(1990, 2030)
end

dates.each do |d|
  puts "#{d.year}-#{d.month}-#{d.day}"
end
