Constant Summary collapse

UNIFORM_PERIODS =

A week is always 7 * 24 * 60 * 60, for instance

[:week, :day, :hour, :minute, :second]
NON_UNIFORM_PERIODS =

e.g. A year may have 365 days or 366

[:year, :month]
PERIODS = 
NON_UNIFORM_PERIODS + UNIFORM_PERIODS
OTHER_PERIODS = 
[:day_of_week, :hour_of_day]
SECONDS_PER_DAY = 
60 * 60 * 24
