Day Sequence Aptitude basics, practice questions, answers and explanations 
Prepare for companies tests and interviews

Day sequence Test: In these question a date given with the day of the week (Monday, etc.....) using that information you will be asked to find out day of other date.

Approach:

1)Find the No. of years and No. of days between the "given date" and "asked date".2)Divide the No. of days by 7.3)Find the reminder of the division.4)If the reminder is '0' then the required day is as same as "given days".5)If the reminder is '1' then the required day is the next day to given day in question date?6)If the reminder is '2' then the required day is two days after the "given date", so on for the 3, 4, 5 and 6 reminders.

Examples:

1) If 15th August is Monday, 17th November comes on which day?Answer: August month has 31 day, September has 30 days and October has 31 days.The number of days between 15th August to 17th November= 16 + 30 + 31 + 17= 94.94/7, it leaves reminder 3. 17th November= 3 days after Monday.i.e. Thursday.2) If 7th February of 2006 is Saturday, 24th April 2006 comes on which day?Answer: 2006 is not a leap year, so February has 28 days, March 2006 has 31 days. The No. of days between 7th February 2006 to 24th April 2006 = 21 + 31 + 24 = 76.76/7, it leaves reminder 6, 24 th April 2006 = 6 days after Saturday = Friday.3) 14th December 2004 is Monday, 25th November 2005 comes on which day? Answer: The No. of days between 14th December 2004 to 25 th November 2005 = 365 - 19 (days gap between 14th December to 25 th November = 19 and 2005 is a normal year) = 346.346/7, it leaves reminder 3; 25th November 2005 = 3 days after Monday = Thursday.4) If 26th March 2006 is Friday, 18th May 2008 is comes on which day?Answer: Days between Step 1 : from 26th March 2006 to 25th March 2007 - 365 days Step 2 : from 26 th March 2007 to 25 th March 2008 – 366 days 26 th March 2008 to 18 th May 2008 = 31 + 22 = 53 days Total days = 365 + 366 + 53 = 784.784/7 = 112, it leaves no reminder.18th May 2008 is also Friday.

Tips:

A year has 365 daysA leap year has 366 daysAny year is divisible by 4 is a leap year e.g. 2004, 2008,.......In normal year, February has 28 days but leap year has 29 days. Hence the leap year has one day extra than normal year.In a normal year, if the year begins with Sunday, it ends with Sunday. The next year starting day will be Monday.In a Leap year, if the year begins with Sunday, it ends with Monday, the starting day of the next year of the leap year will be Tuesday.The no. of days in January = 31 daysThe no. of days in February = 28 or 29 daysThe no. of days in March = 31 daysThe no. of days in April = 30 daysThe no. of days in May = 31 daysThe no. of days in June = 30 daysThe no. of days in July = 31 daysThe no. of days in August = 31 daysThe no. of days in September = 30 daysThe no. of days in October = 31 daysThe no. of days in November = 30 daysThe no. of days in December = 31 daysIn a normal year, it has 52 weeks and one dayIn a leap year, it has 52 weeks and 2 days.

Days between two dates
The date calculator calculates the difference between the 'Start Date' and 'End Date' and displays it in terms of the number of years, months, weeks and days between them. As per the methodology used in this date calculator, a week starts on 'Monday' and ends on 'Sunday'.

Add to or subtract from a date


The date calculator below calculates how far behind or how further ahead will be the date as per the input provided in the 'Start Date' field and the fields below it. The result displayed is a particular date and the day on which it falls.

What is a date calculator?

A date calculator lets you make various kinds of date calculations such as calculating the number of days between two particular dates, knowing how many days have passed since your birth or since you started a job, calculating how many days are left for the next Cricket world cup to begin or for the next Lok Sabha elections, and many more such calculations.

How do the above calculators work?

Working methodology of the 1st calculator

The 1st calculator lets you calculate the difference between two dates, wherein, the first date is termed as 'Start Date' and the latter as 'End Date'. By default, initially, the current date appears in both fields. A user can either enter a past date as the 'Start Date' and calculate the difference between that particular date and the present date or enter a date in the future as the 'End Date' and calculate how far it is from the current date. Alternately, users can also enter both dates as per their choice and check the difference between both dates. The result displayed is in terms of calendar days, which is shown according to the duration of the difference. Additionally, users can choose to include the last day which adds 1 day to the difference by checking the 'Include End Day (add 1 day)' option. As per the methodology used in this date calculator, a week starts on 'Monday' and ends on 'Sunday'.

Working methodology of the 2nd calculator

This calculator can be used to add or subtract some particular number of years, months, weeks or days, individually or combined, from a particular date which is represented by the field 'Start Date' in this calculator. Initially, the 'Start Date' field shows the current date. If need be, users can enter a date of their choice in that field. Now, users need to enter the number of years, months, weeks and days or the number of any individual attribute, as per their choice, in the respective input fields. Next, users need to specify whether to add or subtract that duration from the date by choosing either 'Add +' or 'Subtract -' from the corresponding menu and click on 'Calculate' to get the result. The result displayed is a date and day which is either before or after the 'Start Date' as per the data provided on the input page. As per the methodology used in this date calculator, a week starts on 'Monday' and ends on 'Sunday'.

Various types of Calendars used in India


India, being a hotbed of cultures, is home to people belonging to various ethnicities and following many different religions. This has resulted in Indians following various types of calendars for religious, cultural and official purposes. Though there are numerous, some of the most common types of calendars used in India include the Saka Samvat, Vikram Samvat, the Hijri calendar and the Georgian calendar.

The Saka Samvat lunisolar Hindu calendar is believed to have been introduced by the rulers of the Satavahana dynasty. Quite similar to those used for official purposes, this calendar also has 365 days and 12 months, and in 1957, it was adopted as the 'Indian National Calendar'. However, unlike the official new year's eve, according to the system followed by the Saka Samvat calendar, a new year begins with the onset of the 'Chaitra' month whose first day coincides with March 22 in a conventional calendar or with March 21 if its a leap year.

Similarly, there are some unconventional factors that accompany the Vikram Samvat and the Hijri calendar as well. The Vikram Samvat is a Hindu lunar calendar that is based on the movement of the moon. It has 354 days and 12 months in a year. The months in this calendar are further divided into two phases: 'Shukla Paksha' which begins with a new moon and 'Krishna Paksha' which starts with a full moon. The Hijri calendar is a lunar Islamic calendar that also has 354 days. Followed worldwide, this calendar is used to determine the dates for various Islamic rituals including Ramadan and Hajj.

The calendar used for official purposes


An improvised version of the Julian calendar, the Georgian calendar is used in India as well as various other countries around the world for official purposes. In this calendar, a year is divided into 365 days, with the exception of a leap year, which has 366 days. The total number of days in a calendar year are categorized into 12 months of varying lengths. Each month either has 30 or 31 days, except the month of February which has 28 days in a normal year and 29 days in a leap year.
