distance_of_time_in_words
Ruby on Rails 3.0.20
Since v2.2.3Signature
distance_of_time_in_words(from_time, to_time = 0, include_seconds = false, options = {})Reports the approximate distance in time between two Time or Date objects or integers as seconds. Set include_seconds to true if you want more detailed approximations when distance < 1 min, 29 secs Distances are reported based on the following table:
0 <-> 29 secs # => less than a minute 30 secs <-> 1 min, 29 secs # => 1 minute 1 min, 30 secs <-> 44 mins, 29 secs # => [2..44] minutes 44 mins, 30 secs <-> 89 mins, 29 secs # => about 1 hour 89 mins, 29 secs <-> 23 hrs, 59 mins, 29 secs # => about [2..24] hours 23 hrs, 59 mins, 29 secs <-> 47 hrs, 59 mins, 29 secs # => 1 day 47 hrs, 59 mins, 29 secs <-> 29 days, 23 hrs, 59 mins, 29 secs # => [2..29] days 29 days, 23 hrs, 59 mins, 30 secs <-> 59 days, 23 hrs, 59 mins, 29 secs # => about 1 month 59 days, 23 hrs, 59 mins, 30 secs <-> 1 yr minus 1 sec # => [2..12] months 1 yr <-> 1 yr, 3 months # => about 1 year 1 yr, 3 months <-> 1 yr, 9 months # => over 1 year 1 yr, 9 months <-> 2 yr minus 1 sec # => almost 2 years 2 yrs <-> max time or date # => (same rules as 1 yr)
With include_seconds = true and the difference < 1 minute 29 seconds:
0-4 secs # => less than 5 seconds 5-9 secs # => less than 10 seconds 10-19 secs # => less than 20 seconds 20-39 secs # => half a minute 40-59 secs # => less than a minute 60-89 secs # => 1 minute
Examples
from_time = Time.now distance_of_time_in_words(from_time, from_time + 50.minutes) # => about 1 hour distance_of_time_in_words(from_time, 50.minutes.from_now) # => about 1 hour distance_of_time_in_words(from_time, from_time + 15.seconds) # => less than a minute distance_of_time_in_words(from_time, from_time + 15.seconds, true) # => less than 20 seconds distance_of_time_in_words(from_time, 3.years.from_now) # => about 3 years distance_of_time_in_words(from_time, from_time + 60.hours) # => about 3 days distance_of_time_in_words(from_time, from_time + 45.seconds, true) # => less than a minute distance_of_time_in_words(from_time, from_time - 45.seconds, true) # => less than a minute distance_of_time_in_words(from_time, 76.seconds.from_now) # => 1 minute distance_of_time_in_words(from_time, from_time + 1.year + 3.days) # => about 1 year distance_of_time_in_words(from_time, from_time + 3.years + 6.months) # => over 3 years distance_of_time_in_words(from_time, from_time + 4.years + 9.days + 30.minutes + 5.seconds) # => about 4 years to_time = Time.now + 6.years + 19.days distance_of_time_in_words(from_time, to_time, true) # => about 6 years distance_of_time_in_words(to_time, from_time, true) # => about 6 years distance_of_time_in_words(Time.now, Time.now) # => less than a minute
