How to use DateTime in C#

DateTime

DateTime is a built-in class in C# used to store dates and parse them to and from strings.

Usage

There are various ways to format time in C#:

This example demonstrates how DateTime variables are initialized and then parsed to strings. Parsing to and from a string can be done by comparing the string to a user-defined format.

C# allows users to define their own format using strings. Different components of time are represented in the format as different strings. Some of these are:

1. d represents the day without a leading $0$. It ranges from $1$ to $31$.
2. dd represents the day with a leading $0$. It ranges from $01$ to $31$.
3. ddd represents an abbreviated name for a day like Mon or Tues.
4. dddd represents the full name for a day like Monday or Tuesday.
5. M is the month number without a leading zero. It ranges from $1$ to $12$.
6. MM is the month number with a leading zero. It ranges from $01$ to $12$.
7. MMM is an abbreviated name of a month like Jan or Feb.
8. MMMM is the full name of a month like January or February.
9. y is the year with a minimum of one digit. For instance, 2001 would be $1$.
10. yy is the year with a minimum of two digits. For instance, 2001 would be $01$.
11. yyy is the year with a minimum of three digits. For instance, 2001 would be $001$.
12. yyyy is a four-digit representation of a year. For instance, 2001 would be $2001$.
13. h is the hour in 12-hour notation without a leading zero. For example, 4 AM and 4 PM would both be $4$.
14. hh is the hour in 12-hour notation with a leading zero. For example, 4 AM and 4 PM would both be $04$.
15. H is the hour in 24-hour notation without a leading zero. For example, 4 AM and 4 PM would be $4$ and $16$, respectively.
16. HH is the hour in 24-hour notation with a leading zero. For example, 4 AM and 4 PM would be $04$ and $16$, respectively.
17. m is the minutes without a leading zero. It ranges from $0$to $59$.
18. mm is the minutes with a leading zero. It ranges from $00$ to $59$.
19. s is the seconds without a leading zero. It ranges from $0$ to $60$.
20. ss is the seconds with a leading zero. It ranges from $00$ to $60$.
21. t is a single-character abbreviation for AM and PM. AM will become A and PM will become P.
22. tt is AM and PM.
23. K is the time-zone. For example, $+05:00$.
24. z represents a minimum single-digit offset from the Coordinated Universal Timezone in hours. For example, $+5$.
25. zz represents a minimum two-digit offset from the Coordinated Universal Timezone in hours. For example, $+05$.
26. zz represents an offset from the Coordinated Universal Timezone in hours and minutes. For example, $+05:00$.
27. f represents the decimals in a seconds value. The number of decimal digits is equal to the number of f’s in the format – there can be up to seven f’s. For example, fff may show $224$ for a seconds value of 2:22459 and $000$ for 2:00000.
28. F represents the non-zero decimals in a seconds value. The number of decimal digits is equal to the number of F’s in the format – there can be up to seven F’s. For example, FFF may show $224$ for a seconds value of 2:22459, but it would show nothing for 2:00000.
