Moving wedding date up

Hello!
Originally, the date was for June 2019, but since I decided to take a break from school it’s the perfect opportunity to move the wedding up to March! We don’t have invitations sent or anything.

That’s 3 months away (instead of 6). And on a Monday...but during spring break. I had such a fight from my sister/moh when we talked about that, we decided to keep it June. However I’m still really sure that March is the best time to start our lives together for a few reasons:

I’m the moh in a wedding in July, so it’s easier financially on all of my bridesmaids and myself since we’re all in both weddings and they’re only 3 weeks apart.

My fiancé and I both work in the school district, so we won’t have to take time off from work if it’s during Spring Break.

We already have our photographer who is available, and the venue is open.

The only issues are family members having to take the Monday off from work. But on the other hand it gives us all weekend to prepare! My brother may not be able to make it, and my brother-in-law doesn’t want to fly up during the work week.
Other than that, I know it will be more stressful on myself and fiancé if we keep it in June, because of having to take off time from work AND my friend’s wedding.
I don’t want to postpone the wedding to later in the summer, but my fiancé isn’t wanting to change to March after making the announcement that we were changing the date and then taking it back.

Am I missing out by not taking longer to plan, am I being a pushover by not sticking to the March date change even though it seems like more of an inconvenience to some?
There are so many ways to think about this, I’m just not sure if I should cater to what’s easier on my family, or what’s a more ideal time for me and my fiancé.
