The return value ranges from 1 to 31. (The last day of month differs by months.)

pub fn week(&self) -> u32

Returns the ISO week number starting from 1.

The return value ranges from 1 to 53. (The last week of year differs by years.)

pub fn day_of_year(&self) -> u32

Returns true if the current year is a leap year.

pub fn is_weekend(&self) -> bool

Returns true if the current day is weekend.

pub fn days_in_current_year(&self) -> u32

Returns the start of the current month.

pub fn end_of_current_month(&self) -> Self

Returns the end of the current month.

pub fn start_of_next_month(&self) -> Self

Returns the start of the next month.

pub fn checked_add_months(self, months: u32) -> Option<Self>

Adds a duration in months to the date. Returns None if the resulting date would be out of range.

pub fn checked_sub_months(self, months: u32) -> Option<Self>

Subtracts a duration in months from the date. Returns None if the resulting date would be out of range.

pub fn checked_add_days(self, days: u32) -> Option<Self>

Adds a duration in days to the date. Returns None if the resulting date would be out of range.

pub fn checked_sub_days(self, days: u32) -> Option<Self>

Subtracts a duration in days from the date. Returns None if the resulting date would be out of range.

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Date

fn fmt(&self, f: &mut Formatter<'_>) -> Result
