The editor will share with you what the time functions are in nodejs. I hope you will get something after reading this article. Let's discuss it together.

Time function in nodejs: 1, moment (); 2, format (); 3, diff (); 4, startOf (); 5, endOf (); 6, add (); 7, subtract (); 8, dayjs (); 9, year (); 10, toDate (), and so on.

This tutorial operating environment: windows7 system, nodejs version 12.19.0, DELL G3 computer.

The moment time function applies / / format time moment ('2017-09-01'). Format ('YYYYMMDD') / / current time moment (). Format (' YYYY-MM-DD HH:mm:ss'); / / current time now = moment (); / / format end time endMoment = moment (endDate, 'YYYYMM') / / the interval between the end time and the current time now.diff (endMoment, 'months') / / the previous week startDate = moment (now.join (''), 'YYYYw'). StartOf (' week'). Add (1, 'day'). Format (' YYYY-MM-DD 00 day' 00') EndDate = moment (now.join (''), 'YYYYw'). EndOf (' week'). Add (1, 'day'). Format (' YYYY-MM-DD 23 lastStartDate 59)); / / lastStartDate = moment (now.join (''), 'YYYYw'). Subtract (1,' week'). StartOf ('week'). Add (1,' day'). Format LastEndDate = moment (now.join (''), 'YYYYw'). Subtract (1,' week'). EndOf ('week'). Add (1,' day'). Format ('YYYY-MM-DD 23 day' 59'); / / the previous month startDate = moment (now.join (''), 'YYYYMM'). StartOf (' month'). Format ('YYYY-MM-DD 0000vvvv0000') EndDate = moment (now.join (''), 'YYYYMM'). EndOf (' month'). Format ('YYYY-MM-DD 23 YYYYMM' 59'); / / lastStartDate = moment (now.join (''), 'YYYYMM'). Subtract (1,' month'). StartOf ('month'). Format LastEndDate = moment (now.join (''), 'YYYYMM'). Subtract (1,' month'). EndOf ('month'). Format (' YYYY-MM-DD 23 subtract 59)); / / the start date of the year const startYear = dayjs (). StartOf ('year'); / / the end date of the year const endYear = dayjs (). EndOf (' year'); / / current time const current = dayjs (). StartOf ('day') / / how many days have elapsed in a year other than today const yearStartDay = current.diff (dayjs (). StartOf ('year'), "day"); / / how many days remain in a year const yearEndDay = dayjs (). EndOf (' year') .diff (current, "day"); dayjs time function applies the current time const current = dayjs (); / / current year return dayjs (). Year (); format () returns the formatted date based on the passed placeholder. Dayjs ('2019-01-25'). Format ('DD/MM/YYYY') / /' 25/01/2019'dayjs ('2019-01-25'). Format ('YYYY-MM-DD HH:mm:ss') / /' 2019-01-25 0000 DD01 00' logo example describes the YY18 year, two-digit YYYY2018 year, four-digit M1-December, from 1 to December, two-digit MMMJan-Dec month, abbreviation D1-31 DD01-31 Double-digit H0-2324 hours HH00-2324 hours, double-digit H1-1212 hours hh01-1212 hours, double-digit M0-59 minutes mm00-59 minutes, double-digit S0-59 seconds ss00-59 seconds, double-digit S0-9 milliseconds (100), one-digit SS00-99ms (ten), double-digit SSS000-99ms, three-digit Z-05:00UTC offset ZZ-0500UTC offset, double-digit AAM / PM morning / afternoon, uppercase aam / pm morning / afternoon, lowercase Do1st … The date and serial number of 31st month startOf () sets the beginning of a time, and endOf () sets the end of a time.

/ / set the start of a time dayjs (). StartOf ('year'); / / set the end of a time dayjs (). EndOf (' month') unit abbreviation details yeary on January 1 this year morning 00:00quarterQ the first month of the quarter at 00:00 on the 1st (relying on the QuarterOfYear plug-in) monthM on the 1st of this month 00:00weekw the first day of the week in the morning 00:00isoWeek

The first day of the week at 00:00 (according to ISO 8601) (depending on the IsoWeek plug-in) dateD current time of the day 00:00dayd that day 00:00hourh current time, 0 minutes, 0 seconds, 0 milliseconds minutem current time, 0 seconds, 0 milliseconds seconds current time 0 millisecond Add () increases time / / increases seven days dayjs (). Add (7, 'day') / / minus dayjs (). Subtract (7,' year') subtract () reduces time dayjs (). Subtract (1, 'day') ToDate () returns the original time object dayjs (). ToDate (); after reading this article, I believe you have a certain understanding of "what are the time functions in nodejs".
