This template calculates the date/time difference between two dates. Dates in the Gregorian calendar from 9999 BCE to 9999 CE are supported. The calendar is proleptic—it is assumed to apply at all times with no irregularities.   Syntax   {{time interval|date1|date2|options}}  There are two positional arguments: date1 and date2. The default for each is the current date and time.  The result displays text representing the time interval from date1 to date2 (date2 − date1).  Dates are UTC—local times and time zones are not supported.  Dates are checked for validity. For example, 29 February 2000 is accepted, but 29 February 1900 is not a valid date.  Each date can include an era or a time, and a variety of formats are accepted. Examples of valid dates are: 1900-02-01 1900-2-1 1900-02-01 14:45 1 FEB 1900 February 1, 1900 February 1 1900 14:45 2:45 pm February 1 1900 1 February 1900 2:45 p.m. BC 1 Feb 120  Examples: {{time interval|1 Jan 2001|March 4, 2002}} →  {{time interval|1 Jan 2001|March 4, 2002|abbr=on}} →  {{time interval|B.C.E. 1 Feb 120|28 FEB 1900}} →    Parameters   Parameter  Description abbr=off         Unit names in full (default): year, month, day, hour, minute. abbr=on          Units shown as a single letter with no space between number and unit: y, m, d, h, m. disp=age         If no show has been entered, years are displayed if the age is above 3 years, years and months from 1 to 3 years, or months and days for under 1 year. Sets sep=space by default. This is compatible with . disp=raw         Display numbers only with sep=space. duration=on      Period is a duration (has an extra day to include the end date). format=commas    Numbers over 999 are formatted with commas. format=raw       Use a hyphen (-) to indicate a negative date difference instead of a minus (−); a hyphen may allow the result to be used in a calculation. sep=comma        Separator between items is a comma: 1 year, 2 months, 3 days. The default is 1 year, 2 months and 3 days. sep=,            Same as sep=comma. sep=serialcomma  Use a serial comma: 1 year, 2 months, and 3 days. sep=space        Use a space: 1 year 2 months 3 days. sc=y             Change the default separator to use a serial comma. Also accepts sc=yes and sc=on. show=y           years show=ym          years and months show=ymd         years, months and days (default) show=ymw         years, months and weeks show=ymwd        years, months, weeks and days show=yd          years and days show=m           months show=md          months and days show=w           weeks show=wd          weeks and days show=d           days show=dh          days and hours show=dhm         days, hours and minutes show=dhms        days, hours, minutes and seconds show=ymdh        ymd + hours show=ymdhm       ymd + hours and minutes show=ymwdh       ymwd + hours show=ymwdhm      ymwd + hours and minutes show=h           hours (result would be 48 hours for a difference of 2 days) show=hm          hours and minutes show=hms         hours, minutes and seconds round=on         Round the least-significant unit specified with the show= parameter. round=months     Round to nearest month using show=ym. round=weeks      Round to nearest week using show=ymw. round=days       Round to nearest day using show=ymd. round=hours      Round to nearest hour using show=ymdh. sortable=on      Output a hidden sort key based on the number of days in the date difference (includes a fraction of a day to handle time differences). sortable=off     No sort key (default). sortable=debug   Output a visible sort key for testing.   ব্যবহার    আরও দেখুন
