2018.02.15: The time: 4 new time calculators

Today, main topic The Time... We've finished 4 different calculators related to time:

• Got a Time formats converter - accepts date in many formats and many calendars. 2018-01-30 or 18/30/01 or 20180130 or Islamic or Persian calendar. Even something for geeks: the UNIX timestamp.
  
• The How much time between two dates (two different points in time) - you enter two dates and this calculator finds the number of days between those dates. It can skip public holidays, weekends etc. - all configurable.
  
• The Time (days) to New Year - how many days until we celebrate the New Year ?
  
• The Time (days) to school break - how many days until we are free from school ?
