The data property is design for storing variables, not invoking functions or adding logic like you're trying to do.
Try computed property:
computed: {
tomorrow() {
const d = new Date()
d.setDate(d.getDate() + 1)
return d
}
}
And then in your template you can do {{ tomorrow }} or in your vue component this.tomorrow

Adding days to day-select
Looking at the finished product, we can see that the day select displays an inline list of days, starting from today, and finishing the date a week from now. Let's now add a script tag to the component and import the dayjs library to help us working with dates.

To switch to the next month, we simply add one month to the current startDate value. <template> <div class="buttons"> <button id="next" @click="next">Next</button> </div> <DayPilotScheduler ref="schedulerRef" scale="Day" :days="days" :startDate="startDate" ... /> </template> <script setup> import { DayPilot, DayPilotScheduler } from '@daypilot/daypilot-lite-vue' import { ref, computed } from 'vue' const schedulerRef = ref(null) const startDate = ref(DayPilot.Date.today().firstDayOfMonth()) const days = computed(() => startDate.value.daysInMonth()) const next = () => { startDate.value = startDate.value.addMonths(1) } </script>

v-model on a Date input works with a string in yyyy-MM-dd format. If you're happy to have strings in your model, not date objects, then just put your default date string in the date variable, like this.
date : new Date().toISOString().slice(0,10)
Here's a running example. A name has been changed to avoid having variable names close to reserved keywords!
vm = new Vue({
el: '#vueRoot',
data: { myDate : new Date().toISOString().slice(0,10) }
})<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.js"></script>
<div id='vueRoot'>
<input type='date' v-model='myDate'>
<br>
{{myDate}}
</div>Of course, you may want to have dates as date objects in your model, if you want to format or compare them. In that case, you should avoid v-model and code the two sides of your binding separately, like this.

You could just take the first 7 days (and make sure u start with Monday) to calculate the average temperature and use the following to formate it
const date = moment();
var FormatedDate = date.format('MMM D - ') + date.add(7, 'days').format('D YYYY');
console.log(FormatedDate);
for the days u don't need any format actually, pure HTML would be enough since the first element from the array is Monday and has the temperature for the day too. Hope i could understand your quastion

I have created two different methods, the one that already has been shown above, but outputting the full week days check below.
<div v-for="(country, index) in info" :key="index">
<template v-if="index == 0">
{{ weekDate(country.datetime) }}
</template>
<template v-else>
{{ dayFullName(country.datetime) }}
</template>
{{ Math.floor((country.min_temp + country.max_temp) / 2) }}
</div>
methods: {
weekDate (value) {
const entireWeek = moment(value).format("MMMM D -") + moment(value).add(7, 'days').format("D YYYY")
return entireWeek; // July 6 - 13 2020
},
dayFullName (date) {
const getFullName = moment(date).format('dddd');
return getFullName // Monday, Tuesday etcetera
}

We can then use our method like we would use any Vue method in our template passing in the date want formatted · <template> <p> {{ formatDate('2020-12-25') }} </p> </template> ... We can also use different options. Perhaps we want to show the day of the week. We can do this by adding in the weekday.

Assuming you have a component, like Dashboard.vue, you can use a getter:
<template>
<v-container fluid>
<h1>{{ timestamp }}</h1>
</v-container>
</template>
<script lang="ts">
import { Component, Vue } from 'vue-property-decorator';
@Component
export default class Dashboard extends Vue {
get timestamp() {
const today = new Date();
const date = today.getFullYear() + '-' + (today.getMonth()+1) + '-' + today.getDate();
const time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
const timestamp = date + ' ' + time;
return timestamp;
}
}
</script>

May 1, 2020 - Despite the JavaScript Date warts, it’s straightforward to add day(s) to a date in JavaScript. While it would be very easy to reach for moment.js or another date manipulation library (date-fns, luxon, dayjs) to do something as simple as adding days to a Date in JavaScript, writing a short helper function might just be easier.
