Manipulating Dates with Moment.js

Moment.js formulas let you manipulate stored Date Input values. You can reformat values, for example going from 2020/01/01 to January 1st, 2020. You can also add or subtract units of time, for example adding 7 days to a stored Date Input value.

Formatting Dates

Formatting formulas include tokens, like m, Do, or Y. These tokens represent a way to format your date information. To reformat stored Date Input values, use the following formula template: =moment(moment({Property ID/alias}),'format', '{tokens}'). For example =moment(moment(dateOne),'format', 'YY-MM-DD'). The following tables use Wednesday, January 9th, 1991 as a sample dateOne value.

Presets		Day
Token Outcome Possible Values L 01/09/1991 01-12 / 01-31 / [Year] l 1/9/1991 1-12 / 1-31 / [Year] LL January 9 1991 January-December 1-31 [Year] ll Jan 9 1991 Jan-Dec 1-31 [Year]		Token Outcome Possible Values D 9 1 to 31 Do 9th 1st to 31st DD 09 01 to 31
Day of the Week		Day of the Year
Token Outcome Possible Values d 3 0 to 6 where Sunday = 0, and Saturday = 6 dd We Su to Sa ddd Wed Sun to Sat dddd Wednesday Sunday to Saturday		Token Outcome Possible Values DDD 9 1 to 365 DDDo 9th 1st to 365th DDDD 009 001 to 365
Week of the Year		Month
Token Outcome Possible Values w 2 1 to 53 wo 2nd 1st to 53rd ww 02 01 to 53		Token Outcome Possible Values M 1 1 to 12 Mo 1st 1st to 12th MM 01 01 to 12 MMM Jan Jan to Dec MMMM January January to December
Quarter		Year
Token Outcome Possible Values Q 1 1 to 4 Qo 1st 1st to 4th		Token Outcome Possible Values YY 91 00-99 YYYY 1991 All years

You can also use field separators to visually chunk a date. Acceptable separators include the comma (,), forward slash (/), dash (-), period (.), or space ( ).

Manipulating Dates

To add or subtract units of time from stored Date Input values, use the following formula template: =moment(moment(moment({Property ID/alias}),'{add/subtract}',{number},'{unit(s) of time}'),'format','{tokens}'). For example: =moment(moment(moment(dateOne),'add',10,'days'),'format','YYYY-MM-DD'). The following tables, use the sample dateOne value of Wednesday, January 9th, 1991 (1991-01-09).

Add		Subtract
Formula Outcome =moment(moment(moment(dateOne),'add',3,'days'),'format','YYYY-MM-DD') 1991-01-12 =moment(moment(moment(dateOne),'add',2,'weeks'),'format','YYYY-MM-DD') 1991-01-23 =moment(moment(moment(dateOne),'add',1,'month'),'format','YYYY-MM-DD') 1991-02-09		Formula Outcome =moment(moment(moment(dateOne),'subtract',3,'days'),'format','YYYY-MM-DD') 1991-01-06 =moment(moment(moment(dateOne),'subtract',2,'weeks'')),'format','YYYY-MM-DD 1990-12-26 =moment(moment(moment(dateOne),'subtract',1,'month'),'format','YYYY-MM-DD') 1990-12-09
